Isothermal expansion at temperature T Adiabatic compression Adiabatic expansion (30 pts) In a Carnot engine, an ideal gas is subjected to four reversible steps: isothermal expansion at temperature Th (1+2), adiabatic expansion (2+3), isothermal compression at temperature Tc (34), and adiabatic compression to return to the original position of the engine (4+1). 1.00 mol of gas undergoes a Carnot cycle and for this gas y = 5/3. Let Tc 350 K and Tn = 800 K. If the volume at the start of the cycle is 10 L (point 1), and the volume is 25.0 L after the isothermal expansion (point 2). Calculate: a. The maximum volume of this engine. b. The input heat. c. The total work output. d. The efficiency of this engine. Isothermal compression at temperature TC
