$\displaystyle 1$ g of a liquid is converted to vapour at $\displaystyle 3 \times 10^5 \mathrm{~Pa}$ pressure . If $\displaystyle 10 \%$ of the heat supplied is used for increasing the volume by $\displaystyle 1600 \mathrm{~cm}^3$ during this phase change, then the increase in internal energy in the process will be:
