Question

Learning Goal:
To practice Problem-Solving Strategy 18.1 Ideal Gases.
Lethal concentrations of gases are often expressed in terms
of volume fraction, that is, the fraction of available space
occupied by the hazardous gas. A hazardous-materials
worker wants to calculate the volume fraction of chlorine gas
in a storage room after all of the contents of a 0.900-L
cylinder of chlorine gas at 129 atm is accidentally released
in the room. The environment in the storage room is kept at a
constant pressure of 1.00 atm and a constant temperature of
20.0 °C. The room's dimensions are
8.00m x 8.00m x 2.90m. What is the volume fraction of
chlorine gas present in the storage room?
EXECUTE the solution as follows
Part C
What is the volume fraction of chlorine in the storage room?
Express the volume fraction numerically.
► View Available Hint(s)
volume fraction = 6.26x10
Submit
Part D
EVALUATE your answer
嗬
Correct
When you found the volume fraction of chlorine gas present in the storage room, you had to calculate how the volume of chlorine gas changed as a
result of a decrease in pressure. By what factor did the volume of chlorine gas increase when the gas was released from its container?
Express the ratio of final to initial volumes of chlorine numerically.

Learning Goal: To understand the meaning and the basic applications of pV diagrams for an ideal gas. As you know, the parameters of an ideal gas are described by the equation PV = nRT where p is the pressure of the gas, V is the volume of the gas, 12 is the number of moles. R is the universal gas constant, and T is the absolute temperature of the gas. It follows that, for a portion of an ideal gas, constant. One can see that, if the amount of gas remains constant, it is impossible to change just one parameter of the gas: At least one more parameter would also change. For instance, if the pressure of the gas is changed, we can be sure that either the volume or the temperature of the gas (or, maybe, both!) would also change. To explore these changes, it is often convenient to draw a graph showing one parameter as a function of the other. Although there are many choices of axes, the most common one is a plot of pressure as a function of volume: a pV diagram. pV In this problem, you will…

The absolute value of the work done by the gas during a cycle (a process in which the gas returns to its original state) equals the area of the loop corresponding to the cycle. One must be careful, though, in judging whether the work done by the gas is positive or negative. One way to determine the total work is to calculate directly the work done by the gas during each step for the cycle and then add the results with their respective…
