Which of the following statement is correct regarding melting of ice?

A

It is the phase transformation

B

It takes places at constant pressure and temperature

C

Both (a) and (b)

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
Phase transofmrations also involve in the energy changes. For example, ice requires heat for melting. Normally, this melting takes place at constant pressure and during phase change, temperature remains constant.
