Create a system (refrigerator, heat pump, and heat engine) operating between a hot reservoir at 600 K and a cold reservoir at 289.46 K. Each one should produce 1000 J of useful work. Create a scenario where one of the three systems is “not possible due to first law of thermodynamics”, “not possible due to second law of thermodynamics”, “possible”, and “ideal.”

Given data:
The useful work is: W = 1000 J
The hot reservoir temperature is: TH = 600 K
The cold reservoir temperature is: TC =289.46 K
The heat from hor reservoir is: QH
The heat from the cold reservoir is: QC
The first law of thermodynamics states that, energy comes in the system is equal to the energy going out of the system. There is no loss in energy in the system. Thus, according to the first law of thermodynamics, all these devices are possible.
The second law of thermodynamics from Clausius inequality is,
The device is impossible if,
