During the power stroke in a four stroke automobile engine,the piston is forced down as the mixture of combustion products and air undergoes an adiabatic expansion.Assume that 1.the engine is running at the rate of 2500 cycles/min 2.the gauge pressure right before the expansion is 20 atm, 3.the volumes of the mixture right before and after the expansion are 50.0 and 400 cm^3 respectively 4.the time involved in the expansion is one fourth that of the total cycle and 5.the mixture behaves like an ideal gas with specific heat raio 1.40. Find the average power generated during the expansion?
