WebThe refrigerator extracts heat Q c from a cold-temperature reservoir at T c when the ideal gas expands isothermally. The gas is then compressed adiabatically until its temperature reaches T h, after which an isothermal compression of the gas results in heat Q h being discarded to a high-temperature reservoir at T h. WebPower Cycle and Refrigeration and Heat Pump Cycle : Since the system is returned to its initial state after the cycle, there is no net change in its energy. Therefore, ΔE cycle = 0. Then the equation reduces to. Q cycle = W cycle. This expression can satisfy every thermodynamic cycle, regardless of the sequence of processes followed by the ... could have vs could of
