Halliday, Resnick & Walker β Entropy and the Second Law of Thermodynamics: Problem 31
The efficiency of a particular car engine is 25% when the engine does 8.2 kJ of work per cycle. Assume the process is reversible. What are (a) the energy the engine gains per cycle as heat \(Q_{\text{gain}}\) from the fuel combustion and (b) the energy the engine loses per cycle as heat \(Q_{\text{lost}}\)? If a tune-up increases the efficiency to 31%, what are (c) \(Q_{\text{gain}}\) and (d) \(Q_{\text{lost}}\) at the same work value?
π Solution Approach
Given: 8.2 kJ
Find: (a) the energy the engine gains per cycle as heat \; (b) the energy the engine loses per cycle as heat \
