Problem 00147.
One kilogram of air at a pressure of P = 10^6 Pa and a temperature of T = 500 K expands isothermally so that the pressure decreases by a factor of four. After that, the gas is compressed adiabatically to its original pressure, and then isobarically returned to its original state. Draw a graph of the process in P–V coordinates. Determine the work done by the gas per cycle.
A detailed solution with a brief note of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
