- #14What should be the condition for the efficiency of a Carnot engine to be equal to 1?Ans : Efficiency of Carnot engine, `` \eta =\frac{W}{{Q}_{1}}=\frac{{Q}_{1}-{Q}_{2}}{{Q}_{1}}``
Here,
W = Work done by the engine
Q1 = Heat abstracted from the source
Q2 = Heat transferred to the sink
Thus, for `` \eta =1,W={Q}_{1}or{Q}_{2}=0``, the total heat which is abstracted from the source gets converted into work.
