Determine the change in internal energy of 1.0 L (=1.0 kg) of waterat 1000C when it is fully boiled from liquid to gas, which resultsin 1671 L of steam at 1000C. Assume that the process is done atatmospheric pressure.
[Helpful Hints: Use the First Law of Thermodynamics: Delta U = Q -W]
Helpful Data and Equations:
Q = mL LV = 22.6*105 J/kg W = pDeltaV 1 L = 10-3 m3
