When pressure is increased, the melting point of ice

(A) increases
(B) does not change
(C) decreases
(D) depends on the impurities in the ice

Correct Answer : decreases
Question Asked : SSC Tax Assistant (Income Tax & Central Excise) Exam 2004
Explanation : In this case, if we increase the pressure on the ice the ice-water system wants to try to lower it again. It can do that by making itself fit into a smaller volume. But since water fills a smaller volume when point - allowing more solid to become liquid and hence when we increase pressure, the melting point of ice decreases because of the inversal relationship between the pressure and melting point of ice.
