Gases A(g) and B(g) are confined in a cylinder-and-piston arrangement like that in Figure 5.4 and react to form a solid productC(s): A1g2 + B1g2¡C1s2. As the reaction occurs, the system loses 1150 J of heat to the surroundings. The piston movesdownward as the gases react to form a solid. As the volume of the gas decreases under the constant pressure of the atmosphere,the surroundings do 480 J of work on the system. What is the change in the internal energy of the system?

Question
Gases A(g) and B(g) are confined in a cylinder-and-piston arrangement like that in Figure 5.4 and react to form a solid product
C(s): A1g2 + B1g2¡C1s2. As the reaction occurs, the system loses 1150 J of heat to the surroundings. The piston moves
downward as the gases react to form a solid. As the volume of the gas decreases under the constant pressure of the atmosphere,
the surroundings do 480 J of work on the system. What is the change in the internal energy of the system?
