An ideal gas heat engine operates in Carnot cycle between 227oC and 127oC. It absorbs 6 × 104 cals of heat at higher temperature. Amount of heat converted to work is :-
Answer & explanation
Correct answer: option 4
\(\text{Efficiency : }\eta = \frac{W}{Q}\)
\(\text{Also, } \eta = 1 - \frac{T_2}{T_1}\)
\(\Rightarrow W = Q[1-\frac{T_2}{T_1}] \)
\(\Rightarrow W = 6.0 × 10^4 cal[1 - \frac{127}{227}]\)
W = 2.6 x 104 cal
