$\huge\mathfrak\blue{Answer:}$

We know that the the particles in gasses are packed very losely. They have a lot of gaps between them They move freely. The smell of hot sizzling food reaches us several metres away but to get the smell from cold food we have to go close this is because the particles gain kinetic energy and diffuse rapidly in the air as compared to the cold food.

Kinetic Energy:

Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy that an object has because of its motion.
