Question

An inventor is applying for a patent. He claims his new heat engine can produce 1,200 J of work for every 1,800 J of heat applied to it. In 3-5 sentences evaluate this claim after solving for n. ​

Answer 1

The efficiency of the heat engine is 66.67%.

Efficiency of the heat engine

The efficiency of the heat energy is determined by taking the ratio of the output energy to input energy as shown below;

$\eta = \frac{0utput \ energy}{1nput \ energy} = \frac{1200}{1800} \times 100\% = 66.67\%$

Evaluation of the claim

The efficiency of the heat engine is greater than 50% but less than 75% and can be considered to be moderately efficient.

This implies that the heat engine can convert up-to two-third of the input energy into useful energy.
