A piston-cylinder device contains 0.1 m³ of liquid water and 0.85m³ of steam in equilibrium at 450 kPa (absolute). Heat is transferred at constant pressure until the temperature reaches 300°C.
a. What is the initial temperature of the water?
b. Determine the total mass of water.
c. Determine the internal energy and quality of the water initially.
d. Calculate the final volume
