How do you find the specific volume of R-134A at P=700 kPa and T= 120 C?...

How do you find the specific volume of R-134A at P=700 kPa and T= 120 C? I know it is from the tables but I can't seem to figure out how to get the number: v = 0.43358 m^3/kg

100 kg of R-134a at 320 kPa are contained in a piston-cylinder device whose volume is 7.530 m3. The piston is now moved until the volume is one-half its original size. This is done such that the pressure of the R-134a does not change. Determine the final temperature and the change in the total internal energy of the R-134a. (Round the final answers to two decimal places.)

0.75 kg of refrigerant-134a at 120 kPa and 20°C initially fills a piston-cylinder device. Heat is now transferred to the refrigerant from a source at 150°C, and the piston which is resting on a set of stops, starts moving when the pressure inside reaches 140 kPa. Heat transfer continues until the temperature reaches 90°C. Assuming the surrounding to be at 25°C and 100 kPa, determine (a) the work done, (b) the heat transfer, (c) the exergy destroyed, and (d) the...

A compressor receives 0.1 kg/s R-134a at 150 kPa, -10 degrees C and delivers it at 1000 kPa, 40oC. The power input is measured to be 3 kW. The compressor has heat transfer to air at 100 kPa coming in at 20 degrees C and leaving at 25 degrees C. I'm trying to find the mass flow rate of air, BUT can you please just show me the energy balance and Schematic to set this up. JUST the energy balance...
