QUESTION:

Problem 16PE

Unreasonable Results What is wrong with the claim that a cyclical heat engine does 4.00 kJ of work on an input of 24.0 kJ of heat transfer while 16.0 kJ of heat transfers to the environment?

ANSWER:

Solution 16PE

Step 1 of 2

In heat engine, work output is the difference between the heat transfer into the engine and the heat transfer to the environment. Therefore,

W= Qh- Qc

Here, W is work output of the heat engine, Qh is the heat transfer into the engine and Qc is the heat transfer to the environment.
