An insulated box has a barrier that confines a gas to only one side of the box. the barrier springs a leak, allowing the gas to flow and occupy both sides of the box. which statement best describes the entropy of this system? a) the entropy is greater in the first state, with all the gas on one side of the box. b) the entropy is greater in the second state, with the gas on both sides of the box. c) the entropy is the same in both states, since no heat was added to the gas and its temperature did not change.

1. consider the case in which air fills air shocks on a truck trailer. the pressure in the shocks is 2 mpa. the temperature is 300 k. the diameter of the shock piston is 10 cm and the initial length of the cylindrical cavity containing the compressed air is 40 cm. a. the truck is gradually loaded over a period of a day in a static setting. the temperature is held constant for the atmosphere and thus for the gas shock. calculate the compressibility of the air in the shock for this condition when the truck is initially being loaded. b. if the shocks were loaded in a dynamic setting by driving over bumps, what would be the compressibility? state your assumption. c. what is the initial load on the shock if the shock is in an atmospheric 100 kpa? d. if the shock is compressed using the process described in part a, and the air shock compressed air cavity length decreases to 20 cm, what is the additional load applied to the shock?
