The force exerted by the gas on the piston (see the figure) is the product of the pressure and the area: F = m'zP. piston had (3 The work done by the gas when the volume expands from volume V1 to volume V2 is as follows. \"2 W = P dV \"1 In a steam engine the pressure and volume of steam satisfy the equation Pill-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 120 Ila/in2 and a volume of 100 in3 and expands to a volume of 400 in3.
