The root mean square speed of an ideal gas in a closed container of fixed volume is increased from . Which statement might correctly explain how the change accomplished?
View answer and explanation
Correct option: B
By heating the gas, the pressure is made four times
Option B (By heating the gas, the pressure is made four times) is correct because the root mean square speed is proportional to the square root of the temperature, and pressure is directly proportional to temperature at constant volume.
