Question

2. Give reasons for the following
observation:
The smell of hot sizzling food
reaches you several metres
away, but to get the smell from
cold food you have to go close.​

Answer 1

Explanation:

The smell of hot sizzling food reaches you several metres away, but to get the smell from cold food you have to go close because the kinetic energy of the particles of matter increases with the increase in temperature

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.
