vrms = (3RT/M)1/2
Temperature is directly proportional to the mass.
So for same RMS speed of helium and argon , Argon will have the higher temperature because it has the higher mass. And hence
Argon will be more hot.
A gas of argon atoms and a gas of helium atoms have the same rms speed....
What is the RMS speed of Helium atoms when the temperature of the Helium gas is 448 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?
What is the RMS speed of Helium atoms when the temperature of the Helium gas is 412.0 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?
Helium atoms have a mass of 4u and oxygen molecules have a mass of 32u, where u is defined as an atomic mass unit (u=1.660540×10?27kg). Compare a gas of helium atoms to a gas of oxygen molecules. At what gas temperature Trms would the root-mean-square (rms) speed of a helium atom be equal to that of an oxygen molecule in a gas at 300 K? The answer is not 300 or 37.5
Some incandescent light bulbs are filled with argon gas. What is rms velocity for argon atoms near the filament, assuming their temperature is 1,821 K? Please round your answer to the closest whole number. Given: Atomic mass of argon = 39.95 gm/mol Avogardo's number = 6.02 1023 /mol Boltzmann constant= 1.38 10 23 J/K Equation: mwans - KT I
If the rms speed of the molecules of a quantity of helium at temperature 142 K is the same as the rms speed of neon atoms at a second temperature, what is the temperature of the neon gas? Answer in Kelvins. The answer is NOT 710, 713.55 or 284.
13.4 (a) What is the rms speed of an Oxygen gas molecule (O2) at STP? (b) What temperature would Helium gas have if the rms speed of its atoms was the same as in part (a)? Helium gas is monatomic.

Which of the following is NOT true about helium gas and argon gas samples at the same temperature and pressure? Question 1 options: If you have twice as many moles of argon as helium, the volume of argon will be twice as large. The same number of moles of each will occupy the same volume. One mole each of helium and argon in a container will take up twice the volume of 1 mole of helium by itself. The same...
