Chapter 8, Problem 8.67UTC

A balloon is filled with helium gas with a partial pressure of 1.00 atm and neon gas with a partial pressure of 0.50 atm. For each of the following changes (ato e) of the initial balloon, select the diagram (A, B, or C) that shows the final volume of the balloon: (8.2, 8.3, 8.6)

1. The balloon is put in a cold storage unit (P and n do not change).
2. The balloon floats to a higher altitude where the pressure is less (n and T do not change).
3. All of the neon gas is removed (T and P do not change).
4. The Kelvin temperature doubles and half of the gas atoms leak out (P does not change).
5. 2.0 moles of ${\text{O}}_2$ gas is added (T and P do not change).
