Problem 1PE

Problem        1PE

Relating Heat and Work to Changes of Internal Energy

Gases A(g) and B(g) are confined in a cylinder-and-piston arrangement like that in Figure and react to form a solid product C(s): A(g) + B(g)—>C(s). 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?

If the piston is pulled upward so that it sits halfway between the position shown and the top of the cylinder, is the system still closed?

Consider the following four cases:

(i)        A chemical process in which heat is absorbed

(ii)        A change in which q = 30 J, tv = 44 J

(iii)        A process in which a system does work on its surroundings with no change in Q

(iv)        A process in which work is done on a system and an equal amount of heat is

withdrawn.

In how many of these cases does the internal energy of the system decrease? (a) 0, (b) 1, (c) 2, (d) 3, (e) 4.
