Question

Which is the MOST accurate statement about the heating curve and energy?

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

B) Moving from C to A the temperature decreases but the kinetic energy increases.

C) Although the temperature increases, there is no information about energy change.

D) As time elapses, the substances turns into plasma and has the highest kinetic energy.

Answer 1

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

Explanation: Moving from A to C the temperature and the kinetic energy increases. As the temperature of a substance increases, the movement or kinetic energy also increases.

Answer 2

The answer is A). Moving from A to C the temperature and the kinetic energy increases.
