Question

As a sample of water is heated, the kinetic energy of its molecules increases. Then, the energy is used to overcome the attractions between the molecules so that they are no longer held close together. Which sections of the heating curve illustrate this process?

Answer 1

Answer: SECTION B (BOILING POINT)

Explanation: Boiling point (100°c)

This is the point in which the water molecules acquires sufficient kinetic energy to overcome the attraction binding them.(a point at which a liquid will boil).

When a liquid example water is heated to it's boiling point,there is a rapid vaporization,this is known as boiling.At this boiling point,the temperature of the vapour pressure of the liquid will be directly proportional to the pressure exerted on the liquid by the sorounding atmosphere.
