A thermodynamic system consists of an ideal gas in a cylinder. The gas is compressed from 3.50 L to 2.77 L a constant pressure of 7.0 times 10^4 Pa. what work is involved in this process?

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70°c. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator. (0.00644 kg/s, 800 kpa, 2.03)
