The observation that the smell of hot sizzling food reaches you several meters away, but to get the smell from cold food you have to go close, can be explained by the following reasons:

1. Heat Increases Volatility: When food is heated, it increases the volatility of the substances that produce the smell. Volatility refers to how easily a substance will vaporize, or turn into a gas. When the food is hot, the molecules have more energy, which helps them to vaporize and mix with the air. These aroma molecules then travel through the air and reach our nose, allowing us to smell the food from a distance.

2. Diffusion: The process of diffusion also plays a role in this observation. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. When food is hot, the molecules move faster and spread out more quickly, allowing the smell to diffuse through the air faster and reach our nose even when we are several meters away.

3. Steam Carries Smell: When food is cooked or heated, it often produces steam. This steam can carry the aroma molecules from the food into the air
