An automobile engine, which converts the chemical energy of gasoline to mechanical energy, is between 20 and 30 percent efficient. In other words, only 20 to 30 percent of the original energy stored in the chemical bonds of the gasoline molecules is actually transformed into mechanical energy, or work. This is an example of: the first law of thermodynamics the second law of thermodynamics energy flow in the environment potential energy
