When two blocks of ice are pressed again...

When two blocks of ice are pressed against each other then they stick together (coalesce) because

A

of heat produced during pressing

B

of cold produced during pressing

C

melting point of ice decreases with increase in pressure

D

melting point of ice increases with increase in pressure.

Text Solution

Verified by Experts

The correct Answer is:
C
When the two blocks of ice are pressed together, due to increase in pressure, melting point of ice decreases, ice melts and on removal of pressure, the melting point increases again and it is resolidified. This process is called regelation. Regelation is the phenomenon in which melting of ice occurs due to increase in pressure and re-solidification occurs on removal of pressure.
