To answer your question, the pressure of an ideal gas is proportional to the average kinetic energy of its molecules, which is related to their root mean square speed. If the root mean square speed of the molecules increases by 9 times, their average kinetic energy also increases by 9 times. Therefore, the pressure of the ideal gas also increases by 9 times, assuming that the volume and the number of molecules remain constant.

You can use the following formula to calculate the pressure of an ideal gas:

$$P = \\frac{1}{3}n\\overline{m}v_{rms}^2$$

where $P$ is the pressure, $n$ is the number of molecules, $\\overline{m}$ is the average mass of a molecule, and $v_{rms}$ is the root mean square speed of the molecules.
