Question

Activity to show the smell of hot food reaches to us faster and at a distance then the smell of cold food

Answer 1

Hey friend,

Kinetice energy of particles inceease with the rise in temperature. Smell from the hot sizzling food has vapour which is larger and more energetic. Thus it reaches us several metres away. Smell of cold food has lesser vapour which are not that energetic. They can be only smelled from the close.

Even you can try it out practically or try any activity with diffusion.

Thank you!

Answer 2

When food is hot, diffusion is more. But in cold food diffusion is slow. Hence to get the smell from cold food we have to go close.
