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.
It 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.
This is because the smell volatiles on the food are released more in hot food then in cold food. Food volatiles have low boiling point so the higher the tempeature the more that is released from the food.
The heat coming off releases the smell in the air but cold food is harder to release.
because the smell of the heated food expands in the air and we know that gaseous particles are free to move about.
Heat means that the molecules are moving faster (Brownian motion). This enables them to escape the food's surface more easily. The escaped, floating molecules are what causes the smell.
Smell is the vibration of the etheric body. On heating they expand. Therefore it is better to eat meat and fish cold.
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!
The compounds that are aromatic are released easier when the product is warmer.
Why hot food smell comes faster than cold food
Yes, a dogs sense of smell is ten times stronger than a humans.
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.
14 times stronger than a human's sense of smell
14 times stronger than a human's sense of smell
Something burning is generally stronger than the scent of a candle.
Smell is associated with stronger emotions
Their sense of smell is good but they can only smell things about 20 to 30 feet away.
yes, in fact every other animal on earth has better smell than humans
