Answer

Explanation:

Step1: Recall kinetic - energy and temperature relationship

Kinetic energy of particles is directly related to temperature. Higher temperature means higher average kinetic energy of particles.

Step2: Analyze the heating - curve from A to C

On the heating - curve, moving from A to C, the temperature is increasing. As temperature increases, the average kinetic energy of the particles of the substance also increases.

Step3: Analyze option B

Moving from C to A, the temperature decreases, so the kinetic energy should decrease, not increase.

Step4: Analyze option C

An increase in temperature implies an increase in thermal energy, which is related to kinetic energy. There is information about energy change as temperature changes.

Step5: Analyze option D

There is no indication on the given heating - curve that the substance turns into plasma.

Answer:

A. Moving from A to C the temperature and the kinetic energy increases.
