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 cooling system. If the expanding gases do 451 J of work on the pistons and the sys-tem loses 325 J to the surroundings as heat, calculate the change in energy (E) in J, kJ,and kcal.
