To find the new volume of the nitrogen gas when the pressure is changed to 2.0 atm, we can use the combined gas law formula:
(P1)(V1) = (P2)(V2)
Where:
P1 = initial pressure = 4.0 atm
V1 = initial volume = 4.5 L
P2 = final pressure = 2.0 atm
V2 = final volume (to be determined)
Plugging in the values:
(4.0 atm)(4.5 L) = (2.0 atm)(V2)
18 = 2V2
V2 = 18 / 2
V2 = 9 L
Therefore, the new volume of the nitrogen gas when the pressure is changed to 2.0 atm is 9 L.
A sample of nitrogen gas has a volume of 4.5 L at a pressure of 4.0 atm . The temperature and the number of gas particles do not change.
