Homework Statement
A piston/cylinder contains 2 kg of water at 20 degrees Celsius with a volume of .1 cubic meters. By mistake,someone locks the piston, preventing it from moving while we heat the water to saturated vapor. Find the final temperature and volume and the process work
Homework Equations
I think these are relevant equations?:
specific heat of liquid water is 4.22 kJ/kg*K
specific heat at constant volume is the partial derivative of u (internal energy) with respect to T
The Attempt at a Solution
I'm not sure where to begin. Based on the mass of the water and the value of specific heat I know that the energy required to raise the temperature by 1 kelvin is 8.44. Since the specific heat is the derivative of internal energy I know that if I were to integrate 4.22 with respect to temperature from 293 K to t2 I would get the change in internal energy but t2 is one of the things I don't know
