Thermodynamics Exercises in Work and Heat (Ch3/Ex11)

Consider a piston/cylinder system containing 10 kg of liquid-vapor mixture of water at 100 kPa, with a quality of 25%. The system is now heated and the volume triples. The mass of the piston is such that a cylinder pressure of 200 kPa will float it.
1- Determine the final temperature and volume of the water
2- Find the work done during the process
