In a steam engine the pressure and volume of steam satisfy the equation pv1.4 = k, where k is a constant. (this is true for adiabatic expansion, that is, expansion in which there is no heat transfer between the cylinder and its surroundings.) calculate the work done by the engine during a cycle when the steam starts at a pressure of 160 lb/in2 and a volume of 300 in3 and expands to a volume of 1000 in3.
