One kilogram of boiling water is vaporized to steam at 100 kPa in a frictionless piston-and-cylinder device. Using the Steam Tables, answer the following:

Is the heat needed to vaporize the water to steam equal to the change in enthalpy? Or TDS?
To calculate the work done by the steam, is the first law of thermodynamics equation or the general equation for work applicable?
Is the entropy generation equal to the change in entropy of the water?
Does the heat required for the vaporization of boiling water greater than the work done?

Support your answers with calculations and explanations.

One kilogram of water is contained in a piston-cylinder device at 100 degC. The piston rests on lower stops such that the volume occupied by the water is 0.835 m3. The cylinder is fitted with an upper set of stops. When the piston rests against the upper stops, the volume enclosed by the piston-cylinder device is 0.841 m3. A pressure of 200 kPa is required to support the piston. Heat is added to the water until the water exists as...

1 kg of saturated steam at 1000 kPa is in a piston-cylinder and the massless cylinder is held in place by pins. The pins are removed and the system suddenly and adiabatically expands to 5x its original volume before the piston hits a pair of upper pins. The expansion takes place against an atmosphere is 60 kPa. What is the final specific internal energy of the system? The answer will be in kJ/kg.

A piston-cylinder arrangement containing steam at 200 kPa and 200°C is cooled at a constant volume of 0.5 m3 until it reaches 140 kPa. (a) Calculate the amount of mass of steam in the cylinder (kg) (b) Find the quality (x) of the steam once it reaches 140 kPa Then the piston is allowed to float freely (maintaining a constant pressure, but changing volume), while 50% of the steam is released from the piston. Once the release is done, you...

Saturated water vapor at 1000 kPa is throttled to 100 kPa. The velocity of the steam remains constant through the process. Determine the exit temperature of the water vapor. I know this is already awnsered in a solution for 1st edition but can someone help me understand what they do and how they picked the numbers they did from some table to get the exit temperature?
