Question

An ideal gas is taken through a Carnot cycle. The isothermalexpansion occurs at 280°C, and theisothermal compression takes place at 50.0°C. The gas takes in1000 J of energy from the hotreservoir during the isothermal expansion.

(a) Find the energy expelled to the coldreservoir in each cycle.
1 J
(b) Find the net work done by the gas in each cycle.
2 J

Explanation / Answer

Part 1. Qc = Qh x (Tc / Th) Qc = (1000 J) x ((50+273) / (280+273)) Qc = 584 J Part 2 W = Qh - Qc W = 1000 - 584 = 416 J
