1.) When gasoline burns in an automobile engine, the heat released 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 expanding gases do 451 J of work on the pistons and the system loses 325 J to the surroundings as heat, calculate the change in internal energy in joules.
