Answer to Question #184582 in Molecular Physics | Thermodynamics for Natasha Yvonne Dunn

Question

As a gasoline engine is running, an amount of gasoline containing 14,400 J of chemical potential energy is burned in 1 s. During that second, the engine does 3,600 J of work.

Answer 1

Efficiency is calculated by dividing the output power by input power then multiply by 100.

3600÷14400×100

=25%
