Please post the above answer quickly and as soon as possible..............................
Efficiency of Carnot heat engine depends on temperatures of source and sink and also depends on working substance.Efficiency of Carnot cycle, = (Work done) / (Heat supplied) = W / q1From first law of thermodynamics, q = U + W.Since Carnot cycle is a cyclic process, U = 0 i.e. q = W = Heat absorbed by system = q1 – q2where q2 = heat given out to the sink. = (q1 – q2)/ q1 = 1 – q2/q1 .Also, 1 – T2 / T1.Hence, we can say that efficiency of Carnot heat engine is independent of thermal capacity of source or sink.
A point was missed out in above answer that 100% efficiency cannot be achieved in any of the process.But Carnot cycle is a process which can be most efficient.
