An ideal gas heat engine operates in Carnot cycle between 227^oC and 127^oC. It absorbs 6 × 10⁴ cals of heat at higher temperature. Amount of heat converted to work is :-

2.6 × 10⁴ cals

\(\text{Efficiency : }\eta = \frac{W}{Q}\)

\(\text{Also, } \eta = 1 - \frac{T_2}{T_1}\)

\(\Rightarrow W = Q[1-\frac{T_2}{T_1}] \)

\(\Rightarrow W = 6.0 × 10^4 cal[1 - \frac{127}{227}]\)

W = 2.6 x 10⁴ cal
