A piston-and-cylinder device contains 5 kg of water initially at 150◦C and 0.20 MPa. The frictionless piston is then pushed slowly in an isothermal process until the volume of water becomes 10% of its initial value. Calculate the heat and work exchanged between the device and the surroundings during this process.
Energy balances, W=-P∫dV, etc
The Attempt at a Solution
I am stuck at where to start, as I feel like this is a simple problem but I am making it complicated.
Im not sure what to do since this is a liquid..The work I was doing was for a gas (since I was using the ideal gas law)
Any help would be greatly appreciated.
