Question

Why it is that to smell cold food we can
Be to go close but smell of hot food reaches us several meters away

Answer 1

Explanation:

It is so because the particles of hot food have more kinetic energy and the smell of the hot food reaches several metres away.

In case of cold food, there is less kinetic energy and therefore particles move slowly.

Answer 2

In hot food, the particles are at high temperature so quickly changes to vapour and hence the vapours have greater kinetic energy so travel faster and travel to far off distances.

Whereas in cold food, because of temperature being low, particles do not change to vapour state and hence cannot travel faster so the smell does not reaches to a person sitting far away.
