1.	An ideal gas heat engine operates in a Carnot cycle between `27^(@)C` and `127^(@)C`. It absorbs `6 kcal` at the higher temperature. The amount of heat (in kcal) converted into work is equal toA. `3.5`B. `1.6`C. `1.2`D. `4.8`
Answer» Correct Answer - C Efficiency of a Carnot engine is given by `eta=1-(T_2)/(T_1)` or `W/Q = 1-(T_2)/(T_1)implies W/6=1-((273+27))/((273+127))` `implies W = 1.2 kcal`.
