How does the smell of food reach us?
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 does the smell of hot cooked food reaches us?
The smell of hot cooked food reaches us in seconds. This is due to high speed of particles (kinetic energy) of gases and large space between them shows the property of diffusing very fast into other gases. … Hence gases diffuse faster than solids and liquids.
Why can we smell food when it is being cooked?
There is a phenomenon called Diffusion. In diffusion, molecules of solid, liquid or gas spread from the region of their higher concentration to the region of their lower concentration. … By diffusion, the smell spreads to the whole room and thereby whole house, so anyone standing at a distance, Can smell it.
How the smell of cooking food spread over the entire room?
There is a phenomenon called Diffusion. In diffusion, molecules of solid, liquid or gas spread from the region of their higher concentration to the region of their lower concentration. … By diffusion, the smell spreads to the whole room and thereby whole house , so anyone standing at a distance, Can smell it.
How does the smell of the cooked food reaches our nostrils without entering the kitchen Class 9?
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.
When your mother cooks something in the kitchen you can guess what she is cooking by the smell explain this in terms of molecules?
When my mother cooks food , the aroma spreads across the house and can be smelled . This is because the gas molecules are in random motion and move in every space available to them . Since , they have a lot of kinetic motion within them they spread very fast across the whole house .
How does smell of food being cooked spread so fast 6?
The smell of food being cooked spreads very fast because of the kinetic energy produced. whenever there is an increase in temperature the kinetic energy also increases causing the particles of matter to move fastly by the process of diffusion.
Why does the smell of hot cooked food reaches you several meters away?
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.
Why do gases diffuse very fast?
Gases diffuse very fast because of the presence of large spaces between the gaseous particles and high kinetic energy of these molecules. They diffuse faster than the other states of matter.
Why can you smell things from a distance?
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.
