Heat Engines and the Second Law of Thermodynamics
7PRACTICE PROBLEM
A spacecraft's Carnot heat engine is designed to work between 100℃ and 600℃ to generate energy. This energy powers a Carnot cooling system that regulates the spacecraft's internal temperature. The cooling system works between -10°C and 20°C. Determine, in joules, the ratio of heat energy discharged by the cooling system to the energy consumed by the heat engine.
