Answer. Explanation: the kinetic energy of hot vapours is high so we find that we can smell tea being prepared at home.
Why does smell of food diffuse from a bag to your nose?
Smells travel in the air by diffusion. Because molecules are always moving, some molecules leave the bread as it is baking. They are vented with the excess heat from the oven. These tiny molecules of bread travel through the air throughout the house to our noses.
Why do we get the smell of hot food from a distance but not that of cold food?
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 are we able to smell cooking gas leaks from a distance?
This is due to process of diffusion that one can smell and matter states that molecules in gaseous form can mix well and are not bonded to each other so have weak intermolecular forces.

Hint: Cooked food releases certain gases that gas particles spread out which leads to spreading out the aroma of the food from a distance as those gas particles carry the smell.

The smell of baking cake from the kitchen reaches you in the bedroom, this is because of diffusion. To be more precise, it is the flow of substance and particles which are considered essential as a part of daily life. This mostly occurs in particles of mass in liquid and gases.
How does smell spread by diffusion?
Diffusion in gases
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. They eventually spread through the whole room from an area of high concentration to an area of low concentration.
Why can we smell things from a distance?
Wherever you are— in a classroom, outside, on a bus, at home— you can smell odors because they become part of the air. All odors that humans smell have that in common— they all move as part of the air.
Why the smell of hot sizzling food reaches you several Metres away but to get the small from cold food you have to go close?
> At lower temperatures, particles in cold food have low kinetic energy. 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.
Why does the aroma of hot cooked food reach us while we pass by a restaurant 2?
This is called diffusion. In other words, Hot food increases the temperature of the air around it and hot air circulates faster and extends more as compared to cold air, so the smell of hot food arrives faster than cold food.
Why does food smell more when its hot?
“When it’s hot, the smells in the food around us have more energy and the molecules are more excited, meaning the flavour compounds tend to be in the air more readily. “For example, if you’re in an area where there’s rotting things and it’s hot, the smell is really, really strong.
How does the smell of food being cooked spread so fast Class 6?
Answer : The particles of the aroma of hot cooked food mix with the particles of air spread from the kitchen, reach us and even farther away, in seconds. Due to high speed of particles and large space between them, gases show the property of diffusing very fast into other gases.

Why do we get the smell of hot food from the kitchen outside the house evaporation boiling diffusion sublimation?
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.

What is mean by osmosis in biology?
osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes). The process, important in biology, was first thoroughly studied in 1877 by a German plant physiologist, Wilhelm Pfeffer.

Atoms are constructed of two types of elementary particles: electrons and quarks. Electrons occupy a space that surrounds an atom’s nucleus. Each electron has an electrical charge of -1. Quarks make up protons and neutrons, which, in turn, make up an atom’s nucleus.

Can smell travel underwater?
In practice, smell spreads through water or air via mixing, or currents. The water is always in motion: tides, temperature gradients, wind, fish swimming, Coriolis forces, etc all keep the water moving (though on different scales). This motion of the water carries smell molecules with it.
