As we know, the heat engine works according to the Karnot sword. Then 80% of the amount of heat that we receive from the heater will be transferred to the refrigerator.
It is also known that the amount of heat that we receive is 75 kJ.
Let’s find the work done by the machine at a time, using the following formula:
Efficiency = A / Q1;
A = efficiency * Q1;
A = 0.8 * 75;
A = 60 kJ.
Answer: A = 60 kJ.
