Smell of hot food reaches faster than of cold food because the steam of the hot food mixes with air particles. Air travels around and smell of hot food spreads around. Whereas,
cold food has no steam and therefore we do not get the smell of cold food.

∙ 9y agoIt really comes down to energy. Heat is a form of energy, and if you look at two plates of the same meal and wonder what the differences are, it will be the heat energy exciting the molecules in one and the absence of said activity in the other. The reason hot food gives of a gas is because the heat is causing the molecules in the food to move around which when accelerated enough can form a gas. This can be seen in the evaporation of water when it is boiled. This doesn't mean your food is evaporating only that with sufficient heat the moisture in the food will give off a gas as a result of heat energy exciting the molecules. In Chemistry this would be a transferal of heat energy being turned into kinetic energy, i.e. the movement of the molecules.

∙ 12y agobecause the smell of the heated food expands in the air and we know that gaseous particles are free to move about.

Why does a hot food has a stronger smell than cold food?
Smell is the vibration of the etheric body. On heating they expand. Therefore it is better to eat meat and fish cold.
Why cant you smell cold food from far while you can smell hot food from far?
It is possible to smell food when it is cold. However, it is much easier to smell food when it is hot. The heat gives off thermal energy, which makes it simpler to smell. Because hot food is much simpler to smell, hotter food often tastes better than colder food. If a food smells good to someone, then it often has a better taste, too. Edit: If the cold food has spice on it, then yes! Or if it has garlic in it!
Why does hot food smell better than cold food?
The compounds that are aromatic are released easier when the product is warmer.

Why hot food smell comes faster than cold food
Do dogs sense of smell is ten times stronger than humans?
Yes, a dogs sense of smell is ten times stronger than a humans.
The smell of hot sizzling food reaches you several metres away but to get the smell from cold food we have to go closewhy?
Particles of matter are continuously moving. They possess the kinetic energy. As the temperature rises, particles move faster. Thus, particles that carry smell of hot sizzling food move faster than the smell of the cold food. Therefore, the smell of hot sizzling food can reach us several metres away, but to get smell from a cold food you have to go close.
