Question

We should stress again that the Carnot engine does not exist in real life: It is a purely theoretical device, useful for understanding the limitations of heat engines. Real engines never operate on the Carnot cycle; their efficiency is hence lower than that of the Carnot engine. However, no attempts to build a Carnot engine are being made. Why is that?

A) A Carnot engine would generate too much thermal pollution.
B) Building the Carnot engine is possible but is too expensive.
C) The Carnot engine has zero power.
D) The Carnot engine has too low an efficiency.

Answer 1

good

Step-by-step explanation:

Answer 2

Answer:c

Step-by-step explanation:

Although the Carnot engine is the most efficient it is not feasible in real life. Carnot engine contains processes that are reversible which makes it difficult to build in real life.

For a system to be in equilibrium a system must be in equilibrium with its surroundings in each step and every step which allows it to be infinitely slow.

Due to this slow rate Power of the engine is zero as the work is being done at an infinitely slow rate.
