Question

If the external pressure of ice increases, then the melting point of ice-

a) Increases

b) Decreases

c) Does not change.

Answer 1

If the external pressure of the ice increases then the melting point of the ice will also increase, because the melting point is that temperature at which the vapour pressure of solid becomes equal to the vapour pressure of liquid, and increase in pressure favors freezing of the liquid.
