Whyother than the fact that the second law of thermodynamics says reversible engines are the most ef?cientShould heat engines employing reversible processes be more ef?cient than those employing irreversible processes? Consider that dissipative mechanisms are one cause of irreversibility.
A gun is a heat engine. In particular, it is an internal combustion piston engine that does not operate in a cycle, but comes apart during its adiabatic expansion process. A certain gun consists of 1.80 kg of iron. It fires one 2.40-g bullet at 320 m/s with an energy efficiency of 1.10%. Assume the body of the gun absorbs all the energy exhaustthe other 98.9%and increases uniformly in temperature for a short time interval before it loses any energy by heat into the environment. Find its temperature increase.
