You have 2.5 moles of a gas contained in a 4.2-L bulb at a temperature of 35°C. This bulb is connected to a 18.7-L sealed, initially evacuated bulb via a valve. Assume the temperature remains constant. (a) What should happen to the gas when you open the valve? Calculate any changes of conditions. The gas will flow from the 4.2 L bulb into the 18.7-L bulb. Eventually, the gas will be evenly dispersed throughout the two bulbs v At this...

An ideal gas at a pressure of 1.90 atm is contained in a bulb of unknown volume. A stopcock is used to connect this bulb with a previously evacuated bulb that has a volume of 0.890 L as shown here. When the stopcock is opened the gas expands into the empty bulb. (Figure 1) Figure (1 of 1 Part A If the temperature is held constant during this process and the final pressure is 681 torr, what is the volume...

Problem 9.112 The apparatus shown consists of three temperature-jacketed 1.285 L bulbs connected by stopcocks. Bulb A contains a mixture of H2O(9), CO2(g), and N2(9) at 25°C and a total pressure of 561 mm Hg Bulb B is empty and is held at a temperature of -70°C. Bulb Cis also empty and is held at a 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...

EXAMPLE 19.3. A counterflow induced-draft cooling tower operates with inlet and exit water temperatures of 105 and 85°F when the air has dry-bulb and wet-bulb temperatures, respectively, of 90 and 76°F. The tower has 4 ft of stacked plastic fill, and the flow rates are G, = 2,000 lb/h. ft? and G: = 2,200 lb/h. ft?. (a) Determine the number of transfer units, the...
