Question

The efficiency of a Carnot heat engine
(A) is independent of the temperature of the source and the sink
(B) is independent of the nature of working substance
(C) can be 100%
(D) can be more than 1​

Answer 1

\Answer:

EEfficiency of  Carnot engine is given by η=1−  

T  

2

​  

 

T  

1

​  

 

​  

, where T  

2

​  

 is temperature of source and T  

1

​  

 is temperature of sink.  

Hence, we see that efficiency depend on the temperature of sink and source only and not on the substance.

Answer 2

Explanation:

is independent of the nature of working substance
