Can someone please explain the Carnot Cycle graph in terms of what equations to use and the concepts.

This is what I think but I keep getting mixed up:

Path A to B which is Reversible Isothermal Expansion, Delta U= 0, and according to first law Q= -W and we use RTln V2/V1 for W? In path B to C, the gas expand Adiabatically, so Q= 0 and Delta U= - W. Since it is expansion so the work will be negative. We use the formula W= - Cv (T2-T1) for this path. For Path C to D, it is isothermal compression so do we flip the equation to W= RTln V4/V3 or we can keep it V3/V4 but put the negative sign on it so like - RTlnv3/v4. Finally, for path D to A, it is an adiabatic Compression do we use W= Cv(t2-t1)?

a. Refrigerators make use of the heat cycles, such as the Carnot cycle, but in order to remove heat from the cold source (fridge) and put that energy into the hot source (the enrivonment), another energy source must be added to the system to make this occur. The minimum energy to be supplied follows the equation given below. Find an expression for the coefficient of performance in terms of Th and Tc. coefficient of performance (c) = heat...
