gasses A(g) and B(g) are confined in a cylinder and piston arrangement and react to form a solid product C(s) : A(g) + B(g) = C(s) as the reaction occurs the system looses 1020 J of heat to the surroundings. the piston moves downward as the gasses react to form a solid. as the volume of the gas decreases under the constant pressure of the atmosphere, when surroundings do 460 J of work on the system what is the change in internal energy?
