Question

Explain the following conversion of state on the basis of kinetic theory of matter:
Vapour to liquid

Answer 1

Explanation:

• In the vapour state, particles have enough energy and speed to overcome the intermolecular forces.
• However, with a decrease in temperature and increase in pressure the particles lose some amount of their energy and speed which results in the intermolecular forces being able to pull the particles towards each other.
• The particles are held together by these intermolecular forces constraining them to change their state to liquid.
