Question

Fill in the blanks :

Increase in pressure over ice .................... melting point.

• A. increases
• B. decreases
  
• C. does not change
• D. can't say

Answer 1

The correct option is B decreases

Answer is B

Ice expands as it freezes and contracts as it melts. So with increased pressure it is energetically more favorable to melt than to freeze. In order to remain at the melting point, temperature must decrease to compensate for increased pressure and vice versa.
