Question
Chapter 10, Problem 10.26CP
Interpretation Introduction
(a)
Interpretation:
The representation of gas when the temperature is increased from 300 K to 450 K at constant pressure needs to be determined.
Concept introduction:
When the temperature of a gas is increased, the speed of the gaseous molecules increases. Due to an increase in the speed of the molecules, the space between them increases, hence, the volume of gas increases.
The ideal gas equation is represented as follows:
Here, P is pressure, V is volume, n is the number of moles, R is Universal gas constant and T is temperature.
Interpretation Introduction
(b)
Interpretation:
The representation of gas when pressure is increased from 1 atm to 2 atm at constant temperature needs to be determined.
Concept introduction:
On increasing the pressure, the space between the particles decreases as they come closer to each other. This results in a decrease in the volume.
The ideal gas equation is represented as follows:
Here, P is pressure, V is volume, n is the number of moles, R is Universal gas constant and T is temperature.
Interpretation Introduction
(c)
Interpretation:
The temperature is decreased from 300 K to 200 K and pressure is decreased from 3 atm to 2 atm.
Concept introduction:
When the temperature of a gas is decreased, the speed of the gaseous molecules decreases. Due to the decrease in the speed of the molecules, the space between them decreases, hence, the volume of gas decreases.
Similarly, on decreasing the pressure, the space between the particles increases as they become far from each other. This results in an increase in volume.
The ideal gas equation is represented as follows:
Here, P is pressure, V is volume, n is the number of moles, R is Universal gas constant and T is temperature.

- If equal masses of O2 and N2 are placed in separate containers of equal volume at the same temperature, which of the following statements is true? If false, explain why it is false.

You thought the gas was pure carbon monoxide gas, CO, but you later found it was contaminated by small quantities of gaseous CO2 and O2. Analysis shows that the tank pressure is 1.34 atm (at 24 C) if the CO2 is removed. Another experiment shows that 0.0870 g of O2 can be removed chemically.
