1. The problem statement, all variables and given/known data When a lab associate melts 10.9 g of ice at 0 °C, then heats the liquid to its boiling point and then vaporizes it against 1.0 atm of pressure, find the work done in kJ. 2. Relevant equations work = -Pext(deltaV) 3. The attempt at a solution I found that delta H = 32.836 kJ, but delta h does not equal work. I know that the work, should be the expansion of water from liquid to gas against 1 atm of pressure then i need to convert that value in L-atm to Joules. I just am not sure how to go about getting the change in volume since it is not an ideal gas situation. Or is it?
