Quick Answer: Why Does The Smell Of Hot Cooked Food Reaches You Several Metres Away Within Second?

Why does the smell of hot cooked food spread out easily?

The smell of hot food reaches us faster than cold food, this is because hot temperature affects the movement of the particles in the air.

So the higher the temperature, the faster we smell the scent of the food..

Why it is that to smell cold food we have to go close but smell of hot food reaches us several Metres away?

The smell of hot sizzling food reaches you several meters away, but to get the smell from cold food, we have to go close because the kinetic energy of particles of matter increases with the increase in temperature.

How does the smell of hot cooked food reaches our nostrils?

In cooked food, the particles of matter absorb heat and turn into gaseous state and mix with atmospheric air. So the smell of food reaches our nostrils without our entering the kitchen through air.

Why can we smell hot food from a distance but not cold food?

We smell hot food from distance because of diffusion process. Diffusion is spreading out and intermixing of particles From one substance into another substances due to movement of particles. … As hot food has more temperature , the particles gain Kinetic energy and move with greater speed.

Why does hot food smell more?

Hot food increases the temperature of the air around it and hot air spreads faster and spreads more as compared to cold air, so the smell of hot food comes faster than cold food.

Is smell a Matter?

The sense of smell is not considered a form of matter. However, the smell or odor of a substance is classified as matter. The smell of any substance (say, perfume) is the gaseous form of that substance which our olfactory system can detect (even at very low concentrations).

How does the smell of cooked food reach to us?

In cooked food, the particles of matter absorb heat and turn into gaseous state and mix with atmospheric air. So the smell of food reaches our nostrils without our entering the kitchen through air.

Why does the smell of hot cooked food reaches you several meters away within seconds?

The smell of hot cooked food reaches us in seconds. This is due to high speed of particles (kinetic energy) of gases and large space between them shows the property of diffusing very fast into other gases. In the gaseous state, the particles move about randomly at high speed.

What is the effect of temperature on diffusion?

Temperature: Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion. Solvent density: As the density of a solvent increases, the rate of diffusion decreases.

What is the meaning of hot sizzling food?

adj hot enough to burn with or as if with a hissing sound “a sizzling steak” “a sizzling spell of weather” Synonyms: hot. used of physical heat; having a high or higher than desirable temperature or giving off heat or feeling or causing a sensation of heat or burning.
