7. You have 2.4 moles of gas contained in a 4.0-L bulb at a temperature of 32 °C. This bulb is connected to a 20.0-L sealed, initially evacuated bulb via a valve. Assume the temperature remains constant. Please answer the followings. (10%)

(A) What should happen to the gas when you open the valve? Calculate any changes of the conditions.

(B) Calculate ΔH, ΔH, q, and w for the process you describe in part a.

(C)Given your answer to part b, what is the driving force for the process?
