  1. Question 1

    Q1. The efficiency of a Carnot engine is 50%. The temperature of the sink is 27°C. The temperature of the source is

    • A) 327°C
    • B) 127°C
    • C) 227°C
    • D) 300°C

    Answer: 327°C

    Explanation: Efficiency = 1 - (T_sink / T_source). Given efficiency = 0.5, T_sink = 300K, we can solve for T_source = 600K or 327°C.
