Question

If
pressure is
applied, what happens to
metting point of solid that expands
when heated and contracts when heated,

​

Answer 1

Pressure: For the solids, those expand on heating, the melting point increases with increase in the pressure. It is due to the fact that the pressure opposes the increase in the distance between molecules (expansion). ... For the solids, those contract on heating, the melting point decreases with increase in the pressure.
