Solution

Q.
Work done by a Carnot engine operating between temperatures 127°C and 27°C is 2 kJ. The amount of heat transferred to the engine by the reservoir is [2023]

1 8 kJ

2 4 kJ

3 2.67 kJ

4 2 kJ

Ans.
(1)

$Efficiency of Carnot engine$

$η = 1 - \frac{T_{2}}{T_{1}} = \frac{W}{Q_{1}}$ $\Rightarrow \frac{W}{Q_{1}} = 1 - \frac{300}{400} = \frac{1}{4}$

$\Rightarrow \frac{2 kJ}{Q_{1}} = \frac{1}{4}$

$\Rightarrow Q_{1} = 8 kJ$
