at first step the pressure of a fixed amount of a monatomic gas is increased at the constant volume from the initial pressure P to the pressure aP where a is an arbitrary coefficient. at the second step the gas is isothermally expanded and at the third step the gas is compressed at a constant pressure and returns back to the initial condition. What is the efficiency of this heat engine cycle?

A heat engine composed of 1.6 moles of an ideal, monotonic gas is initially at 350 K and 1x10^5 Pa. The first step is an isothermal expansion to a pressure of 5x10^4 Pa. Second, the gas is compressed at constant pressure back to the inital volume. Finally the gas returns, at constant volume to the initial state. What is the total work done by the gas during this cycle? What is the efficiency of this cycle?

A three-step cycle is undergone by 3.8 mol of an ideal diatomic gas: (1) the temperature of the gas is increased from 230 K to 710 K at constant volume; (2) the gas is then isothermally expanded to its original pressure; (3) the gas is then contracted at constant pressure back to its original volume. Throughout the cycle, the molecules rotate but do not oscillate. What is the efficiency of the cycle?

A mole of a monatomic ideal gas is taken from an initial pressure p and volume V to a final pressure 3p and volume 3V by two different processes: (I) It expands isothermally until its volume is tripled, and then its pressure is increased at constant volume to the final pressure. (II) It is compressed isothermally until its pressure is tripled, and then its volume is increased at constant pressure to the final volume. Show the path of each process...
