Answer 1

HEYA ❤️

The smell of hot sizzling food reaches you several meters away but to get the smell from cold food you have to go close. This is because of diffusion. As the temperature increases the kinetic energy is also increased. So that at high temperature the particles of hot food move fastly as compared to cold food.

Answer 2

$\large{\boxed{\red{\textbf{Thanks \: for \: asking }}}}$

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.
