hey mate

this is because of diffusion the smell of hot sizzling food is in high volume but

a person stand few meters away have its low volume

we can also say density in place of volume

and as we know gas move from high density place to low density place

so that is why we get the smell of food few metres away

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.
