In an ideal heat engine, the absolute temperature of the heater differs from that of the refrigerator by 2.5 times. What is the efficiency of this machine?
To calculate the efficiency of the specified heat engine, we apply the formula: η = 1 – Тх / Тн.
Relationship of variables: Тн (abs. Heater temperature) = 2.5 Тх (abs. Refrigerator temperature).
Let’s perform the calculation: η = 1 – Tx / 2.5Tx = 1 – 0.4 = 0.6 (60%).
Answer: The efficiency of this heat engine is 60%.
