1kg liquid and gaseous water
100°C
1 atm
One kilogram of liquid water at 100°C is vaporized to steam at 100°C in a piston. (Equilibrium can be assumed). What procedure is needed to determine how much heat would be required and how much work is done in this process? If Q does not equal W, what accounts for the difference?
