External pressure on ice at 0^(@)C is in...

External pressure on ice at `0^(@)C` is increased from 1 to 1.2 atm

A

It has no effect on the melting point of ice

B

It increases the melting point of water

C

It decreases the melting point of water

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
`underset("More volueme")("Ice") hArr underset("Less volume")("Water" ( At " "0^(@)C))`
High pressure shifts the equilibrium in the forward direction i.e., more of ice melts to form water. It is posible only if melting point of ice decrases.
