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.

And as the kinetic energy of particles of hot sizzling food is high so it can be smelled from metres away.

Particles in the air, if fueled with higher temperatures, acquire high kinetic energy which aids them

to move fast over a stretch. Hence the smell of hot sizzling food reaches a person even at a distance of several meters.
