Question

Which of the following would double the pressure on a contained gas at constant temperature?

Answer 1

Answer: C. doubling the number of particles in the container

Explanation: According to the ideal gas equation:'

$PV=nRT$

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.

$P\propto n$

Therefore, the pressure will double when number of moles or number of particles double.
