Part (a)  The second step in the Otto cycle is isochoric (constant-volume) heating. Calculate the heat absorbed by the gas during this process, in joules, if the temperature is increased so that T3 = 1.53T2.  Part (b)  Calculate the pressure at the end of the isochoric heating step, in pascals, to three significant figures.  Part (c)  The third step in the Otto cycle is adiabatic expansion, which brings the volume back to its initial value. Calculate the work preformed on the gas, in joules, during the third step.  Part (d)  The fourth and last step in the Otto cycle is isochoric cooling to the initial conditions. Find the amount of heat, in joules, that is discharged by the gas during the fourth step.  Part (e)  Calculate the efficiency of this Otto cycle, expressed as a percent.
