Answer to Problem 8Q

Solution:

No, heat engine efficiency e=W/QL doesn't hold good.

Explanation of Solution

The definition of heat engine efficiency e=W/QL is not true. The efficiency formula should contain the energy input and output work. Also, the given equation is not useful because if the exhaust energy QL is less than work done W, the efficiency can exceed unity.
