(1) A cycle with ideal gas operates as follows: (i) From an initial state (p1, V1) the gas is cooled at constant pressure to (p1, V2); (ii) The gas is heated at constant volume to (p2, V2); (iii) The gas is expanded adiabatically back to (p1, V1). Show that the efficiency of this cycle is (V1 – V2) – 1 n = 1- y- (р, — Р2) — 1

Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.
