Question

In each cycle of a Carnot engine, 93 J of heat is
absorbed from the high-temperature reservoir
and 58 J is exhausted to the low-temperature
reservoir. What is the efficiency of the engine?

Answer 1

The efficiency of the engine is defined to be:

where[i] W[/i]-is the work done by the system (energy exiting the system as work),

[i]Q[sub]H[/sub][/i] is the heat put into the system (heat energy entering the system),

[i]Q[sub]C [/sub][/i]is the heat exhausted to the low-temperature reservoir.
