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
A gas of argon atoms and a gas of helium atoms have the same rms speed. Which gas is hotter? Explain your answer. (Note: the mass of an argon atom is greater than the mass of a helium atom)
Calculate the density of oxygen, O2, under each of the following conditions: STP 1.00 atm and 35.0 ∘C Express your answers numerically in grams per liter. Enter the density at STP first and separate your answers by a comma. To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 4.8-L bulb, then filled it with the gas at 1.40 atm and 30.0 ∘C and weighed it again. The difference in mass was 7.5 g ....
The escape speed from the Earth is 1.12×104m/s, so that a gas molecule travelling away from Earth near the outer boundary of the Earth's atmosphere would, at this speed, be able to escape from the Earth's gravitational field and be lost to the atmosphere. Part A At what temperature is the average speed of oxygen molecules equal to 1.12×10^4m/s? Part B At what temperature is the average speed of helium atoms equal to 1.12×10^4m/s?
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.
