Expansion Problem

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?

Solutions

1. What is going on in the piston?

2. How do I calculate work?

3. How do I calculate heat?

4. Real life applications
