Thermodynamics efficiency:
Review
Problem:A car engine burns gasoline and the burnt gas reaches a temperature of 1000 degreesF. he gas is exhausted at 200F.
Calculate the thermodynamic efficiency f this engine if there are no other energy losses.
Internal energy: kinetic energy of motion of atoms and molecules
KE of molecules 3/2 kT
