Question:medium

The efficiency of a Carnot engine working between temperatures $127^\circ\text{C}$ and $27^\circ\text{C}$ is}

Show Hint

Remember that for a Carnot engine, the efficiency depends only on the temperatures of the hot and cold reservoirs. Always convert temperatures to Kelvin before applying the formula.
