Question

an ideal reversible engine is the one which has
a)highest efficiency b)100% efficiency​

Answer 1

Answer:

highest efficieny

Explanation:

Any reversible heat engine (which is ideal engine) can't be 100 % efficient.

Because it violates second law of thermodynamics. Which states heat energy can't be converted into equal amount of work energy. Means there should be some losses has to occur. That's why output energy will be always less than input inergy. Therefore efficient will be less then 100%.

Efficiency of reversible engine is maximum .

Answer 2

Answer:

Explanation:Carnot engine is an ideal reversible engine and lines of book are as under
