Q379
A large iceberg melts at the base, but not at the top, because of the reason that
A.
Ice at the base contains impurities which lowers its melting point
B.
Due to the high pressure at the base, its melting point reduces
AnswerC.
The iceberg remains in a warmer condition at the base
D.
All of the above
Answer: Option B
Solution
Answer: Option B
Solution:
We can say by Le Chatelier's principle on increasing the pressure the system will react in an way to minimize the effect( the volume decreases) so, generally substances tend to form solid but in case of water the as the liquid occupies less volume than solid the high pressure tends to form liquid (melting).
