A gas within a piston-cylinder assembly executes a Carnot power cycle during which the isothermal expansion occurs at TH = 600 K and the isothermal compression occurs at TC = 300 K.

Determine:

a) the thermal efficiency. Answer: 50%

b) the percent change in thermal efficiency if TH increases by 15% while TC remains the same.

c) the percent change in thermal efficiency if TC decreases by 15% while TH remains the same.

d) the percent change in thermal efficiency if TH increases by 15% and TC decreases by 15%(with sketch)
