Question

Why do we smell hot food from a distance ( physics )?

Answer 1

When food gets cooked, it releases some aromatic gases into the air. The molecules of these gases spread and mix with air molecules. When this air reaches our nose, we get the smell offood. ... Thus, the rate of diffusion decreases and we cannot smell thefood from a distance.

Answer 2

when food get cooked , it released some aromatic gas into the air . the molecules of this gases spread and mix with air molecules .when this air reach to our nose,we get some offood. ........... Thus,the rate of diffusion deceases and we cannot smell the food from a distance .
