1. When gasoline burns in an automobile engine, the heat released (325 J) causes the products CO2 and H20 to expand, which pushes the pistons outward. Excess heat is removed by the car's cooling system. If the work associated with the expanding gases is equal to 451 J, how much is the change in internal energy of the gases? How much is the change in internal energy of the piston?
Please answer it. Thanks!
