In an ideal heat engine, the absolute temperature of the heater is 2 times the temperature of the refrigerator. Find the efficiency of the machine?
The efficiency is equal to the ratio (Tn-Tx) / Tn * 100%. So, from the condition Tн = 2Tx. substitute in the formula: ŋ = (2Tx-Tx) / 2Tx = Tx / 2Tx = 1/2 = 0.5. Percentage: 0.5 * 100% = 50%.
Answer: 50%
