Water, with a pressure of 800 kPa and a quality of 0.334 undergoes a constant pressure expansion process to four times the initial volume. Find the work done on the system and the final temperature of the water.

The process above continues in the path of a linear expansion of pressure with respect to volume until the final pressure is 1200 kPa and the final temperature is 1000 °C. Find the work done on the system during this process.

Helium undergoes a polytropic process from an initial state of 20 °C and 100 kPa to a final pressure of 1 MPa. The polytropic exponent is 1.5. Find the specific work of the process and the final temperature.

Helium is compressed in a constant temperature process at 20 °C from 100 kPa to 1 MPa. Find the specific work of the process.
