Question

(C) When ice melts into water at $273 \ K$,the density of water is greater than that of ice,which means the volume of the system decreases $(dV < 0)$.

Vedclass · Accepted Answer

The internal energy of the ice-water system increases.

Vedclass · Answer

(C) When ice melts into water at $273 \ K$,the density of water is greater than that of ice,which means the volume of the system decreases $(dV Since work done $W = P \Delta V$,and $\Delta V$ is negative,the work done by the system on the atmosphere is negative (or work is done on the system by the atmosphere).Therefore,option $(b)$ is incorrect.During the phase change,heat is absorbed by the system from the surroundings,which increases the internal energy of the system.Thus,only statement $(c)$ is correct.
