A scientist says that the efficiency of his heat engine which operates at source temperature 127°C and sink temperature 27°C is 26%, then
  • a)
    It is impossible
  • b)
    It is possible but less probable
  • c)
     It is quite probable
  • d)
    Data are incomplete
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
A scientist says that the efficiency of his heat engine which operates...
Carnot Engine, a reversible heat engine has maximum efficiency when operating between two temperature limits.
So more the 25% efficiency is not possible.
