MCQ
If heat is supplied to a solid, its temperature:
  • A
    Must increase.
  • B
    May increase.
  • C
    May remain constant.
  • Both $B$ and $C$

Answer

Correct option: D.
Both $B$ and $C$

When heat is supplied to a solid, it is used up either to increase the temperature of the body or to change its state from one form to another by breaking the bonds between the molecules $($without raising the temperature$).$
When heat is supplied to the solid, the internal energy of the solid increases, so the temperature does not decrease.
