When gasoline burns in a car engine, the heat released causes the products CO2 and H2O to expand, which pushes the pistons outward. Excess heat is removed by the car's radiator. If the expanding gases do 541 J of work on the pistons and the system releases 523 J to the surroundings as heat, calculate the change in energy (AE) in J. O 1064J -18J O-1064J 18J
