An ideal gas heat engine operates in a Carnot's cycle between $227^\circ \mathrm{C}$ and $127^\circ \mathrm{C}$ . It absorbs 6 × 10 4 J at high temperature. The amount of heat converted into work is ....
Text Solution
Verified by ExpertsThe correct answer is:
D
$\eta = 1 - \frac{T_2}{T_1} = 1 - \frac{400}{500} = \frac{1}{5} \quad \therefore \eta = \frac{W}{Q} \Rightarrow \frac{1}{5} = \frac{W}{Q} \Rightarrow W = \frac{Q}{5} = \frac{6}{5} \times 10^4 = 1.2 \times 10^4 \mathrm{J}$
