Draw a T-v diagram of a pure substance including the liquid, vapor, and liquid/vapor region. Using this diagram, explain what happens if a saturated liquid is heated (such that the temperature rises) in a rigid (constant volume) container. Using the same diagram, explain what happens when a saturated vapor is heated (such that the temperature rises) in a rigid container.

Must the amount of heat absorbed as 1 kg of saturated liquid water boils at 100 °C, be equal to the amount of heat released as 1 kg of saturated water vapor condenses at 100 °C? Why? Which process requires more energy: completely vaporizing 1 kg of saturated liquid water at 1 atm pressure or completely vaporizing 1 kg of saturated liquid water at 8 atm pressure? Why? A food-scientist is cooking three identical beef stews in pans that are...

A mass of 5 kg of saturated liquid-vapor mixture of water is contained in a piston- cylinder device at 125 kPa. Initially. 3 kg of the water is in the liquid phase and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 300 kPa. Heat transfer continues until the total volume increases by 10%. We denote the...

In a well-insulated rigid tank which contains 2 kg of a saturated liquid-vapor mixture of water at 200 kPa
In a well-insulated rigid tank which contains 2 kg of a saturated liquid-vapor mixture of water at 200 kPa, 40% of the mass is in the liquid phase. A heater is providing heat to the content of the tank so that all liquid phase converts to vapor phase. Calculate the entropy change of water in this process.
