Answer: C. doubling the number of particles in the container
Explanation: According to the ideal gas equation:'
[tex]PV=nRT[/tex]
P= Pressure of the gas
V= Volume of the gas
n= number of moles
T= Temperature of the gas
R = gas constant
As the gas is contained in a container with fixed volume and temperature is also constant.
[tex]P\propto n[/tex]
Therefore, the pressure will double when number of moles or number of particles double.
