Question

How does the average potential energy of molecules of substance change during its change in phase a constant temperature- on heating-It increasesIt decreasesIt does not changeCan-t say

Toppr Admin · Accepted Answer

Answer is AThe heat energy added during the phase change is used to overcome some of the forces that hold the molecules together- allowing them to move further away from each other- During the phase change- the added heat energy is stored as potential energy
