Question

what happened to the melting point of solid when pressure is increase??​

Answer 1

Explanation:

Melting it would increase the volume of that substance because liquids take more space than solids. If you increase the pressure, it becomes harder for that transformation to occur. ... Because ice takes more volume than liquid water, it's actually easier to melt it at high pressure and it requires less heat.

Answer 2

a) No effect

b) The melting point increases when the air pressure increases

c) The melting point decreases when the air pressure increases

The boiling point has inverse relation with vapor pressure of the liquid and positive relation with atmosphere (air) pressure. The melting point has positive relation with vapor pressure of the substance.
