Question

At melting point, *

A.Kinetic energy remains same but potential energy increases

B. Kinetic energy increases but potential energy remains same

C.Both Kinetic energy and Potential energy increases

D. Both Kinetic energy and Potential energy Decreases
​

Answer 1

Answer:

During a change of phase, the average kinetic energy of the molecules stays the same, but the average potential energy changes. ... My interpretation is that during a phase change, the temperature remains equal, but the kinetic energy of its particles increase/decrease.
