Imagine a 600 g of water at 70oC in a piston-cylinder device. Initially, the 9-kg, 13-cm diameter piston rests on two stops such that the water occupies a volume of 0.2 m3. Heat is transferred to the system until the water is completely vaporized. Take the atmospheric pressure to be 1 atm.
To what temperature should the water be heated to lift the piston?
