Question

The smell of hot food reaches you if you are several meters away but to get the smell of a cold food you have to go close​

Answer 1

Answer:Kinetic Energy

Explanation:

Because the aroma spreads in air and air being a gas has less space between molecule when it is heated the temperature rise so there is rise in kinetic energy. And as kinetic energy increases the molecules move faster.

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.
