Please show your work for these two questions

Superheated steam, 0.15 kg, at a temperature of 300 Degree C and an unknown pressure is compressed in a closed system until a saturated vapor at 300 Degree C is reached. During this isothermal compression process, a heat loss of 16.317 kJ is noted. Assume the temperature of the surroundings is 27 Degree C. What was the initial pressure (kPa)? 6000 5000 7000 5280 Superheated steam at 10 MPa and 800 Degree C enters an adiabatic turbine and exits at 800 kPa. Neglecting changes in kinetic and potential energy, what is the exit temperature (Degree C)? 323.9 363.2 333.3 349.75
