velocity (root mean square) = sq. rt.[(3*R*T) / (molar mass of gas)]
R = ideal gas constant; T = temperature in kelvins
as you can see, if the velocity is doubled, the temperature will increase by a factor of 4 (because of the square on velocity)
according to Gay-Lussac's law, P/T = constant, so if temperature T is increased by a factor of 4 (basically temperature is multiplied by 4), the same thing will happen to P
so as an overall, if the speed doubled for this gas, pressure P and absolute temp T will both increase by a factor of 4 (or their values will be multiplied by 4)
