A heat engine receives 6 000 J of heat from its combustion process and loses 4 000 J through the exhaust and friction.What is its efficiency?

Question

Quizplus · Accepted Answer

The efficiency of a heat engine is calculated as (Work output / Heat input) * 100%. The work output is the heat input minus the heat lost, which is 6,000 J - 4,000 J = 2,000 J. Therefore, the efficiency is (2,000 J / 6,000 J) * 100% = 33%.
