One gram of water is placed in a cylinder and the pressure is maintained at 2.0×105 Pa. The temperature of the water is raised by 31C°. Determine the change in internal energy when, a) the water is in its liquid phase and causes an expansion of 1.0×10−8 m3 and b) water is in its gaseous phase and expands by a much greater amount of 7.1×10−5 m3. Assume that there is no phase change for both cases. CliquidH20=4186 J/(kgC°), CgasH20=2020 J/(kgC°).
