Can pressure be changed without changing the volume? If yes, how?

Pressure can be increased by adding an inert gas into the container! However, the inert gas won't cause any changes in the equilibrium of the chemical equation. Additionally, pressure can also increase if you increase the temperature, as they are both directly proportional to each other (PV=nRT).

Increasing temperature increases pressure, and we know this because of the ideal gas law.

Pressure can be changed by changing the temperature or adding an inert gas without changing the volume.

If you look at the equation pV = nRT changing either temperature or inert gas (if volume remains constant) will change pressure.

For the effect of something like pressure, use the ideal gas law PV=nRT. Increasing something on one side will increase something on the other side.

You can do this by increasing the temperature.

Increasing the temperature will increase the pressure and other factors can change pressure if you consider the equation PV=nRT.
