Gas at a pressure of 0.85 bar, volume 0.25m^3 and temperature 18°c, is compressed until the pressure is 2.8 bar and volume is 0.115m^3, calculate the compression index and the final temperature.

6–55 refrigerant-134a enters the condenser of a residential heat pump at 800 kpa and 358c at a rate of 0.018 kg/s and leaves at 800 kpa as a saturated liquid. if the compressor consumes 1.2 kw of power, determine (a) the cop of the heat pump and (b) the rate of heat absorption from the outside air.
