A 1.00-mol sample of an ideal monatomic gas is taken through the cycle shown in Figure. The process A → B is a reversible isothermal expansion. Calculate (a) the net work done by the gas, (b) the energy added to the gas by heat, (c) the energy exhausted from the gas by heat, and (d) the efficiency of the cycle. (e) Explain how the efficiency compares with that of a Carnot engine operating between the same temperature extremes.

Problem 1:   In this problem a heat engine, each cycle, absorbs an amount of energy Qh = 1915 J from a hot reservoir and expels an amount Qc = 1325 J into a cold reservoir. Each cycle lasts for a time of t = 0.34 seconds. Part (a)  Find the efficiency of an ideal engine operating between these reservoirs. Remember the efficiency is unit-less, therefore so should your number be as well.   Part (b)  How much work, in Joules, is done per cycle at this efficiency?  Part (c)  How much power, in Watts, does the engine output per cycle at this efficiency?  Part (d)  What if the actual work done (more realistically) is W = 320 J during a single cycle; what is the efficiency of this engine if the energy input is the same (again, the number should be unit-less)?

A 4.00 L sample of a diatomic ideal gas with specific heat ratio 1.40, confined to a cylinder, is carried through a closed cycle. The gas is initially at 1.00 atm and at 300 K. First, its pressure is tripled under constant volume. Then, it expands adiabatically to its original pressure. Finally, the gas is compressed isobarically to its original volume. (d) Find the temperature at the end of the cycle. K   (e) What was the net work done on the gas for this cycle?J
