Question

In which of the compound is rate of diffusion is faster:
(A) Faster in liquids than in solids and gases.
(B) Faster in gases than liquids and solids.
(C) Faster in solids than in liquid and gases.
(D) None of these.

Answer 1

Hint :For solving this question first of all we should be aware of what is diffusion. The movement of a substance from high concentration to low concentration is known as diffusion. It generally happens in liquids and gases as their particles move randomly from place to place.

Complete step by step solution:
Diffusion occurs due to the random movement of the particles. Diffusion will occur mostly where the intermolecular forces are weaker.
We know that gases have weaker intermolecular forces compared to liquid and solids. Hence diffusion will be high in gas.
Examples of diffusion:-
When we immersed a tea bag in a cup of hot water, then it diffused into the water and the color of the water changed.
When we generally spray perfume or a room freshener then it will get diffused into the air hence we are able to sense the odor.
When we dissolve sugar in water then it will dissolve evenly and sweetens the water.
Factors affecting diffusion:
Diffusion generally depends upon the temperature.
It also depends upon the area of Interaction.
Diffusion generally depends upon the size of the Particle.
It also depends upon the steepness of the concentration gradient.
As from the above it is clear that the rate of diffusion depends upon the temperature, hence the rate of diffusion is faster in gas as in higher temperature gases molecules have high kinetic energy.
Thus, the option B, is correct.

Note:
As diffusion is very important in our life but it has some disadvantages. Some of disadvantages are:- Whenever a poisonous snake or insect bites, then the poison will diffuse into the body and A small leak in the gas container causes leakage of the gas.
