How does the smell of food being cooked in the kitchen reach us even from a considerable distance?

The smell of food cooked in the kitchen reaches us even from a considerable distance because the tiny particles of the vapour of food mix with the air and move continuously in all directions. This process is called diffusion.

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.

When your mother cooks food you can smell the food across the House Why?

When my mother cooks food , the aroma spreads across the house and can be smelled . This is because the gas molecules are in random motion and move in every space available to them . Since , they have a lot of kinetic motion within them they spread very fast across the whole house .

Why the smell of hot cooked food reaches us in 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.

The kinetic energy of particle is more in hot food so their diffusion rate is also high that’s why the smell of hot food reaches us several metres away…. Usually,when the food is cooked at that time evaporation is occur and food smell is also comes out through evaporation.

Why can’t we smell cold food?

Why is hot sizzling tasty?

Temperature’s taste spectres

Heating or cooling certain parts of the tongue can create the illusion of certain tastes. A study published in the journal Nature in 1999 found that, for example, warming the front edge of the tongue (where the chorda tympani nerve is), from a cold temperature, can evoke sweetness.

Does hot food smell more?

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.

How does smell travel through air?

A smell is created when a substance releases molecules (particles) into the air. … Smells travel through the air by a process called diffusion; air particles, and the odour particles within the air, move freely in all directions. They are constantly moving and eventually they spread out through the air around them.
