Q3
An actual engine is to be designed having same efficiency as the Carnot cycle. Such a proposition is
A.
Feasible
B.
Impossible
AnswerC.
Possible
D.
Possible, but with lot of sophistications
Answer: Option B
Solution
Answer: Option B
Solution:
According to the Carnot theorem, no engine operating between two constant temperature reservoirs can be more efficient than a Carnot engine operating between the same reservoirs. This means that achieving the same efficiency as the Carnot cycle with an actual engine is impossible, as it would violate the second law of thermodynamics.
Therefore, the correct completion is: "An actual engine is to be designed having same efficiency as the Carnot cycle. Such a proposition is Impossible."
