What is the RMS speed of Helium atoms when the temperature of the Helium gas is 247 K? (Possibly useful constants: the atomic mass of Helium is 4.00 AMU, the Atomic Mass Unit is: 1 AMU = 1.66×10-27 kg, Boltzmann's constant is: kB = 1.38×10-23 J/K.)
What would be the RMS speed, if the temperature of the Helium gas was doubled?
sq rt of 3RT/M

is that the right equation to use? I am having a hard time with this one
