Concept explainers
(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.
(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.
(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.

- 5.19 A sample of CO2 gas has a pressure of 56.5 mm Hg in a 125-mL flask. The sample is transferred to a new flask, where it has a pressure of 62.3 mm Hg at the same temperature. What is the volume of the new flask?arrow_forwardA typical barometric pressure in Redding. California, is about 750 mm Hg. Calculate this pressure in atm and kPa.arrow_forwardA collapsed balloon is filled with He to a volume of 12.5 L at a pressure of 1.00 atm. Oxygen, O2, is then added so that the final volume of the balloon is 26 L with a total pressure of 1.00 atm. The temperature, which remains constant throughout, is 21.5 C. (a) What mass of He does the balloon contain? (b) What is the final partial pressure of He in the balloon? (c) What is the partial pressure of O2 in the balloon? (d) What is the mole fraction of each gas?arrow_forward
