An аir cоmpressоr used with а pаint sprayer dоes 64.0 J of work pumping air into a tank. Warmed by the process, the air in the tank gives off 32.0 J of energy to its surroundings. What is the change in the internal energy of the air in the tank because of the two processes? 1.ΔE = -30 J 2.ΔE =+30 J 3.ΔE = -32 J 4.ΔE = +30 J 5.ΔE = 32 J ΔE =q+w
