The smell of hot cooked food reaches us in seconds as compared to cold food, which one of the best description this phenomina?

Due to high speed of particles and large space between them, gases show the property of diffusing very fast into other gases.

The pressure exerted by the gases on the cooking food is higher as compared to atmospheric pressure.

Due to mixture of hot food particles with air is increses the movement of particles.

In the gaseous state the particles move randomly at high speed due to gravitional forces.

Explanation:

A gas is a compressible fluid. Not only will a gas conform to the shape of its container but it will also expand to fill the container. In a gas, the molecules have enough kinetic energy so that the effect of intermolecular forces is small (or zero for an ideal gas), and the typical distance between neighboring molecules is much greater than the molecular size. A gas has no definite shape or volume, but occupies the entire container in which it is confined. A liquid may be converted to a gas by heating at constant pressure to the boiling point, or else by reducing the pressure at constant temperature
