A typical car gas tank holds 15 gallons. (a) Calculate the energy content of this much gasoline. (b) calculate the chemical energy content of 15 gallons of hydrogen gas under normal atmospheric pressure (12.8 MJ/m3 as described under Equation 11.4), and compare your answer with the energy in the gasoline. Your answer shows why pressurizing, liquefying, or chemically combining hydrogen is necessary in hydrogen- powered vehicles.
