Hot air travels faster than cool air, because it is lighter than cool air. Smell(food) molecules are hot, so they reach our nostrils by travelling faster than normal air.
How does the smell of the cooked food reach our nostrils without entering the kitchen?
How does the smell of the cooked food reach our nostrils even without our entering the kitchen? Answer: The particles of aroma of food mix with the particles of air through diffusion and reach our nostrils. Thus, we get the aroma of the food without entering in kitchen.
How the smell of food being cooked in the kitchen does reaches us even from a considerable distance class 9?
The smell of food cooked in the kitchen reaches us even from a considerable distance because the tiny particles of the vapour of food mix with the air and move continuously in all directions by the process of diffusion.
How the smell of food being cooked in the kitchen does reaches us even from a considerable distance?
The smell of food being cooked reaches us even from a considerable distance is because of the process of diffusion.
How does smell of food being cooked spread so fast?
When we increase temperature, the particles move with more speed and gain kinetic energy. Hot food has a very high temperature. Thus it spreads to a very large distance. So we can say that we smell hot food from a distance because of diffusion.
How does the smell of food reach your nose?
Smells reach the olfactory sensory neurons through two pathways. The first pathway is through your nostrils. The second pathway is through a channel that connects the roof of the throat to the nose. Chewing food releases aromas that access the olfactory sensory neurons through the second channel.
How does the smell reaches our nostril?
Hot air travels faster than cool air, because it is lighter than cool air. Smell(food) molecules are hot, so they reach our nostrils by travelling faster than normal air.
What do you think is the best explanation why we could smell what is baking in the kitchen when we are inside the bedroom?
Why do we smell bread baking throughout the house? The answer is diffusion. A good way to describe diffusion is the moving of molecules from a place where they are concentrated close together to a place where they are less concentrated or farther apart. When molecules are spread out evenly, diffusion seems to stop.
How does smell of food being cooked spread so fast for Grade 6?
Answer : The particles of the aroma of hot cooked food mix with the particles of air spread from the kitchen, reach us and even farther away, in seconds. Due to high speed of particles and large space between them, gases show the property of diffusing very fast into other gases.
How are you able to smell a flower or food that is being cooked?
Hint: Cooked food releases certain gases that gas particles spread out which leads to spreading out the aroma of the food from a distance as those gas particles carry the smell.
What is diffusion Class 9?
The process of movement of a substance (solid, liquid, or gas) from the region of higher concentration to the region of lower concentration so as to spread uniformly is called diffusion.
When you come home from school and open the door you can smell food being cooked?
Answer. Explanation: the kinetic energy of hot vapours is high so we find that we can smell tea being prepared at home.
Why do we get the smell of hot food from the kitchen outside the house?
Hot food increases the temperature of the air around it and hot air spreads faster and spreads more as compared to cold air, so the smell of hot food comes faster than cold food.
Why do we get the smell of hot food from a distance but not that of cold food Class 9?

When a bottle of perfume was opened in a room we can smell it even from a considerable distance Why?
The particles of perfume start diffusing around the air and moves from lower concentration by virtue of their kinetic energy. Was this answer helpful?
How is smell connected to taste?
The chemical senses include taste and smell. The perception of a smell occurs when substances in the air pass through the nose and stimulate the olfactory (smell) nerve. The experience of taste, or gustation, occurs when the taste buds in your mouth respond to substances dissolved in saliva.
How does the smell sense work?
How does my nose work? Molecules are released by substances around us. When they enter your nostrils, they can stimulate receptors located on the olfactory sensory neurons in the back of the nose. Those neurons send messages to your brain, which identifies the smell.
How do we smell food?
These food odors or odorants are detected by receptor proteins on hair-like cilia at the tips of the sensory cells in your nose, which in turn send neural messages to the brain – these two messages are what we would perceive as a flavor or taste.
What part of the nose detects smell?
Up on the roof of the nasal cavity (the space behind your nose) is the olfactory epithelium (say: ol-FAK-tuh-ree eh-puh-THEE-lee-um). Olfactory is a fancy word that has to do with smelling. The olfactory epithelium contains special receptors that are sensitive to odor molecules that travel through the air.
Can you smell without a nose?
If you pick up a grapefruit and take a whiff, the fruit’s molecules stimulate olfactory cells in your nose. Those cells immediately send signals to your brain, where electrical pulses within an interconnected group of neurons generate a smell’s sensation.
Where do smells go?
When you smell a smelly substance, odorant molecules travel to your nose, where they bind to olfactory receptor cells (6), which generate electrical signals that are sent to a part of your brain called the olfactory bulb (1). Also shown are (2) mitral cells, (3) bone; (4) olfactory epithelium, and (5) glomerulus.
How does the kinetic theory explain how you can smell coffee and bacon at the same time?

Why does my bedroom smell like poop?
because an empty or ‘dried-out’ P-trap is by far the most common cause of all sewer-gas smells. Each and every plumbing fixture and/or plumbing drain has a P-trap on the drain if it has been installed according to Code, and it’s these P-traps that protect us from sewer-gas.
What happens when we smell food?
When your smell and taste nerves are stimulated, signals are sent to the brain, where they and translated to identify what we are tasting. When we’re hungry, the brain boosts the sense of smell to improve our chances of finding food.
Why does my toilet smell like body odor?
If you have a damaged wax ring located at the bottom of the toilet, underneath, it can allow some airflow and sewer gas to leak into the bathroom. If you have a rocking toilet, this can be the cause of the odors and urine smells. Sewer organisms that seep into the house side of a toilet trap. A clogged plumbing vent.
How do smells spread?
Smells travel through the air by a process called diffusion; air particles, and the odour particles within the air, move freely in all directions. They are constantly moving and eventually they spread out through the air around them.
Can you smell food cooking?

What is mean by osmosis in biology?
osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes). The process, important in biology, was first thoroughly studied in 1877 by a German plant physiologist, Wilhelm Pfeffer.
What is osmosis very short answer?
In biology, osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell’s partially permeable membrane.
Why are you able to smell things across a room or from great distances when you are not near the source of the smell?
Wherever you are— in a classroom, outside, on a bus, at home— you can smell odors because they become part of the air. All odors that humans smell have that in common— they all move as part of the air.
Why do cold food not smell from a distance?
Answer: Temperature or heat raises particle kinetic energy. The scent of hot food diffuses with air. Thus the smell of the hot food reaches us at a significant distance whereas cold food cannot.
How does the smell of food reach your nose?
Smells reach the olfactory sensory neurons through two pathways. The first pathway is through your nostrils. The second pathway is through a channel that connects the roof of the throat to the nose. Chewing food releases aromas that access the olfactory sensory neurons through the second channel.
How does the smell of food being cooked in the kitchen reaches us even from a considerable distance?
The smell of food cooked in the kitchen reaches us even from a considerable distance because the tiny particles of the vapour of food mix with the air and move continuously in all directions by the process of diffusion.
How can the smell of hot food reaches to you when you away from it but for smelling cold food you have to go closer to it explain why?
The smell of hot sizzling food reaches you several meters away, but to get the smell from cold food, we have to go close because the kinetic energy of particles of matter increases with the increase in temperature. Was this answer helpful?
Why do we get the smell of hot food from the kitchen outside the house evaporation boiling diffusion sublimation?
The kinetic energy of particle is more in hot food so their diffusion rate is also high that’s why the smell of hot food reaches us several metres away…. Usually,when the food is cooked at that time evaporation is occur and food smell is also comes out through evaporation.
Why does the smell of freshly baked cake reaches fast to our nostrils than the smell of ice cream?
At lower temperatures, particles in cold food have low kinetic energy. At higher temperatures, particles have high kinetic energy and move faster hence, due to this smell of hot sizzling food reaches you several meters away, but to get the smell from cold food you have to go close.
How does the smell of food being cooked spread so fast?
When we increase temperature, the particles move with more speed and gain kinetic energy. Hot food has a very high temperature. Thus it spreads to a very large distance. So we can say that we smell hot food from a distance because of diffusion.
How can the scent of a perfume spread in each corner of our home explain?
Expert-verified answer
When a bottle of perfume is opened in a corner of a room, the scent soon spreads all over the room. This physical procedure is called diffusion, due to which the liquid or gaseous molecules travels from the area of higher density to that of the lower density of that substance.
How does the smell spread in the entire room?
Molecules of the scent fill the spaces between air molecules and the molecules of air fill the spaces between scent molecules due to diffusion. So, the odour of the scent spreads in the room.
Can you taste a fart?
You won’t be able to taste a fart that escapes through your mouth. Flatulence is made up of swallowed air and gas produced by bacteria in the colon from undigested carbohydrates. It smells bad due to the breakdown of various foods into certain gases, primarily sulfur-containing gases.
Can you taste without a tongue?
Reba], a sensory neuroscientist at the National Institutes of Health. Ryba and his colleagues found that you can actually taste without a tongue at all, simply by stimulating the “taste” part of the brain—the insular cortex.
Can we taste without smell?
The sense of smell also enhances your ability to taste. Many people who lose their sense of smell also complain that they lose their sense of taste. Most can still tell between salty, sweet, sour, and bitter tastes, which are sensed on the tongue.
How is smell connected to taste?
The chemical senses include taste and smell. The perception of a smell occurs when substances in the air pass through the nose and stimulate the olfactory (smell) nerve. The experience of taste, or gustation, occurs when the taste buds in your mouth respond to substances dissolved in saliva.
What is the sense of smell called?
Olfaction is the sensation of smell that results from the detection of odorous substances aerosolized in the environment. Along with vision, taste, hearing, and balance, olfaction is a special sense. Humans are able to detect odors through the components of the olfactory system.
How does your nose smell?
When you smell an odor, you’re actually breathing in tiny molecules. These molecules stimulate specialized nerve cells, called olfactory sensory neurons, high inside the nose. There are a few million of these cells inside your nose.
Why does the aroma of hot cooked food reach us while we pass by a restaurant?
Hot food increases the temperature of the air around it and hot air spreads faster and spreads more as compared to cold air, so the smell of hot food comes faster than cold food.

What happens if you cut off an ear?
Can the victims still hear and smell? Yes, but with more difficulty. The outer part of your ear, known as the pinna, funnels sound into your ear canal, like a megaphone in reverse. If someone cut it off, everything would sound quieter.
Why do I smell like the food I eat?
Your breath might smell like the food you eat, but not your sweat. Body odor is created when the bacteria on our skin metabolize the compounds that come out of our sweat glands. “The sweat doesn’t come out smelly,” Preti explains. “It must be metabolized by the bacteria that live on the surface of the skin.”
