a) for each step, stete whether the heat, work, and change in internal energy (e.g. q.,w,AU, ) is greater than, less than or equal to zero (no equations are necessary). i.e. the heat and work for the entire process? Justify b) What are the signs of quot and wrot, your reasoning (no equations are necessary). c) Explain the key design difference in the cycle that determines whether the system acts as a heat engine or heat pump.
