Question

Diffusion is the spontaneous mixing of different particles having freedom of
movement.
Some situations are given below.
● An incence stick is burnt.
● A drop of ink is added into a glass of water.
● Blue ink is dropped on a piece of chalk.
a) In which situation diffusion takes place faster?
b) Explain the reason based on the movement of particles.
c) How does temperature affect diffusion?

Answer 1

Answer:

a) ink on water is faster

Answer 2

Answers as per different situations is as follows -

a) Diffusion will be faster in the case when An incence stick is burnt. This is because speed of diffusion is most in gases, in comparison to liquids and solids.

b) Possession of kinetic energy helps in movement of the particles, which eventually results in diffusion.

c) Increase in temperature increases the kinetic energy of particle and hence rate of diffusion increases.
