WebThe coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) … WebWell, let's look at the First Law of Thermodynamics. The First Law holds, for any thermal process in here, whether it's an isotherm, an isobar, any of them, so we can say that ΔU has got to equal Q, which is the heat that flows into a gas, plus W, which is the work done on the gas, and now we know, for an isothermal process the ΔU is just 0.
