3 2 points How does the thermal efficiency of an ideal cycle

3. (2 points) How does the thermal efficiency of an “ideal cycle” compare to that of a “Carnot cycle” operating between the same temperature limits? (Select the best response.)

a) It is less than the thermal efficiency of a Carnot cycle.

b) It is greater than the thermal efficiency of a Carnot cycle.

c) The two terms are equivalent, so the thermal efficiencies will be equal.

d) Not enough information given.

Solution

a) It is less than the thermal efficiency of a Carnot cycle

because there r many ideal cycles like otto,diesel ,etc having less efficiency than carnot.

for ideal cycle each process should be reversible.
