A sample of $0.1\text{g}$ of water at $100^{\circ }\text{C}$ and normal pressure ($1.013\times 10^5{\text{Nm}}^{-2}$) requires $54\text{cal}$ of heat energy to convert to steam at $100^{\circ }\text{C}$. If the volume of the steam produced is $167.1\text{cc}$, the change in internal energy of the sample, is:

1. A
   $42.2\text{J}$
2. B
   $208.7\text{J}$
3. C
   $104.3\text{J}$
4. D
   $84.5\text{J}$
