Solution

Pressure

Pressure of an ideal gas is given by PV = \[\frac{1}{3}mn u^2\] .

We know that pressure depends on volume, number of molecules and root mean square velocity. Also, root mean square velocity depends on the temperature of the gas. Since the number of molecules, volume and temperature are constant, pressure of the gas will not change.
