The apparatus shown consists of three temperature jacketed 1.585 L bulbs connected by stopcocks. Bulb A contains a mixture of H2O(g), CO2(g), and N2(g) at 25°C and a total pressure of 561 mmHg. Bulb B is empty and is held at a temperature of -70°C. Bulb C is also empty and is held at temperature of -190°C. The stopcocks are closed, and the volume of the lines connecting the bulbs is zero. CO2 sublimes at -78°C, and N2 boils at -196°C. (Figure 1)
The stopcock between A and B is opened, and the system is allowed to come to equilibrium. The pressure in A and B is now 214 mm Hg. What do bulbs A and B contain?
