Question

PROBLEMS 1. /Two containers, A and B, are separated by a tap as in Figure 10-1 as a volume of 15 liters and contains one mole of ideal gas at 25°C. B has a volume of 45 liters and is completely evacuated. Calculate the change in entropy which occurs when the tap is opened. What is the corresponding change in free energy? n the previous problem, the system loses free energy when the tap is opened. What happens to the free energy which is lost? 3. If an ideal gas is suddenly compressed, does its temperature essarily increase? 4. Three molecules of neon are added to the system shown in Figure 10-4. What is the probability of finding one of these in container A and two in container B? What is the probability of finding all three in container A?

Explanation / Answer

2.The free energy which is lost can be used to do some work by the system externally.

3. When an ideal gas is suddenly compressed, its temperature definitely increase. Sudden change is adiabatic.
