A increases Correct Answer Incorrect Answer
B does not change Correct Answer Incorrect Answer
C decreases Correct Answer Incorrect Answer
D depends on the impurities in the ice Correct Answer Incorrect Answer

Solution

In this case. if we increase the pressureontheicetheice-watersystemwantsto 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 it's liquid, rather thansolid,it will gotoalower meltingpoint — allowingmoresolidtobecomeliquidandhence when we increase pressure,the meltingpointof icedecreasesbecauseoftheinversalrelationship between the pressure and melting point of ice.
