Answer 2

THE DIFFERENCES ARE AS FOLLOWS

MELTING POINT:

• gradual change of state from solid to liquid by absorbing heat from surrounding .
• heat is required to supply for external source for such change of state.
• internal energy of the substance also increase for melting.

FREEZING POINT:

• gradual change of state from liquid to solid by leaving heat to surrounding.
• heat is required to take away from the substance for this change of state.
• internal enrgy of the substance decreases in case of freezing .
