Home > Chemistry > Measuring Gas Pressure

If 4 moles of gas are added to a container that already holds 1 mole of gas, what happens to the pressure inside the container due to the change in the amount of gas?

Answer 1

The pressure increases fivefold.

Pressure is directly correlated with the number of molecules and, consequently, the number of moles at constant volume and temperature.

This is immediately apparent from the Ideal Gas equation:

i.e. #P_1# #=# #(nxxRxxT)/V#

#P_2# #=# #((n+4n)xxRxxT)/V# #=# #5P_1#

The pressure inside the container increases due to the addition of gas. According to Boyle's Law, the pressure of a gas is inversely proportional to its volume at constant temperature, assuming the amount of gas remains constant. Therefore, adding more gas to the container increases the number of gas particles colliding with the walls of the container, resulting in an increase in pressure.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
