Determine the efficiency of the heat engine if the amount of heat received from the heater is 4 times the amount of heat given to the refrigerator.
Given: Q1 (the amount of heat that was received by the heat engine from the heater) = 4Q2 (the amount of heat that the heat engine gave to the refrigerator).
The efficiency of a heat engine is determined by the formula: η = ((Q1 – Q2) / Q1) * 100%.
Substitute the given values and determine the efficiency: η = ((4Q2 – Q2) / 4Q2) * 100%. = 3/4 * 100% = 0.75 * 100% = 75%.
Answer: The efficiency of a heat engine is 75%.
