1. The problem statement, all variables and given/known data You have a sealed container with 2kg of water (molar mass: 18g/mol, density: 1000kg/m^3). The lid on the container is very light, and the container side walls are very tall, like a tall graduated cylinder. You start with the water at room temperature 25 C and boil all the water until you get to 200 C. What is the work done by he water molecules. 2. Relevant equations 3. The attempt at a solution[/b I'm not really sure how to go about starting this. If someone could give me a set of equations or explanation it would be much appreciated.
