The efficiency of the steam engine is 78.9%.
<h3>What is the efficiency of a machine?</h3>
The efficiency of a machine is a measure of the useful work done by the machine as against the work input into the machine.
- Efficiency of a machine = work output/work input × 100%
Work output of the steam engine = 225 K
Work input of the steam engine = 285 K
The efficiency of the machine = 225/275 × 100% = 78.9%
Therefore, the efficiency of the steam engine is 78.9%.
