Explanation: It is because of a phenomena called “diffusion”. … The particles of these gases move very quickly and mix up with air by diffusion. When the air containing these gases reaches your nose, you get the smell of food being cooked in the kitchen(even without entering the kitchen).
How the smell of food being cooked in the kitchen does reaches 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 by the process of diffusion.
How does the smell of cooked food reaches us?
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. … Due to this random movement, the particles hit each other and also the walls of the container.
Why does the smell of good food diffuse from a container to your nose?
Smells travel in the air by diffusion. Because molecules are always moving, some molecules leave the bread as it is baking. … These tiny molecules of bread travel through the air throughout the house to our noses. Have you ever passed by a bakery and noticed the delicious smells down the street from it?
When your mother cooks something in the kitchen you can guess what she is cooking by the smell explain this in terms of molecules?
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 .
How does this smell reach us?
For us to detect the smell, those molecules need to enter our nose. … 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.
Why do you usually smell the food being cooked by your neighbor?
Property manager Michael Wolfe of Midboro Management says he most often hears complaints about cooking with fish or strong spices–and that the most common explanations for drifting odors include cooking on a stove without a vent hood, a clog in the building ventilation system and/or the stovetop vent hood, or a defect …
Why does the smell of hot cooked food spread out easily?
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.
Why do the smell of hot sizzling food reaches you several Metres away but to get the smell from cold food you have to go close?
Particles of cold food possess less kinetic energy and are not able to reach several meters away. … At higher temperatures, particles have high kinetic energy and move faster hence, due to this smell of hot sizzling food reaches you several meters away, but to get the smell from cold food you have to go close.
When a bottle of perfume was opened in a room?
When a bottle of perfume in opened, fragrance of perfume spreads in the whole room. This behaviour is due to larger spaces in between the tiny particles of gas and their random movements which leads to the process of diffusion.
How does the smell of food which is being cooked in the kitchen reaches to our drawing room explain the phenomenon involved?
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 smell spread by diffusion?
Diffusion is driven by differences in concentration. When chemical substances such as perfume are let loose in a room, their particles mix with the particles of air. The particles of smelly gas are free to move quickly in all directions. … Remember that the particles still move, even when the smell is evenly spread.
Can you smell the food that my mother is cooking?
Answer: The particles of aroma of food mix with the particles of air through diffusion and reach our nostrils. Thus, we get the aroma of the food without entering in kitchen.
What type of change will take place when your mother cook food for you?
Cooking Food is an example of chemical change.
