Calculate the efficiency of the motor if it received 150 MJ of heat from the heater, and transferred 100 MJ to the refrigerator.
Initial data: Q1 (the amount of heat that this engine received from the heater) = 150 MJ; Q2 (the amount of heat given off during operation to the refrigerator) = 100 MJ.
The motor efficiency can be calculated using the formula: η = (Q1 – Q2) / Q1 * 100%.
Let’s calculate: η = (150 – 100) / 150 * 100% = 50/150 * 100% = 33.3%.
Answer: The engine efficiency is 33.3%.
