The heat machine received heat Q1 = 800 J from the heater and performed work A = 280 J. Determine the efficiency of the machine.
Initial data: Q (energy received by the heat engine from the heater) = 800 J; A (the work that the heat engine was able to do) = 280 J.
The efficiency of a heat engine with the given parameters can be calculated by the formula: η = (A / Q) * 100%.
Calculation: η = (280/800) * 100% = 35%.
Answer: The efficiency of the heat engine is 35%.
