A certain thermodynamic engine extracts 1.30 kJ of thermal energy from a hot temperature reservoir and discharges 0.70 kJ of energy to a cold temperature reservoir.What is the efficiency of this engine?

Question

Quizplus · Accepted Answer

The efficiency of a thermodynamic engine is calculated using the formula: Efficiency = (Work output / Heat input) * 100%. The work output is the difference between the heat input and the heat discharged: 1.30 kJ - 0.70 kJ = 0.60 kJ. Thus, Efficiency = (0.60 kJ / 1.30 kJ) * 100% = 46%.
