The rms speed of oxygen molecules is 460 m/s at 0°C. The atomic weight of an oxygen atom is approximately 4 times the atomic weight of a helium atom. However, the helium molecule is monatomic whereas the oxygen molecule is diatomic. The rms speed of helium at 40°C is approximately O 880 m/s 440 m/s O 1.08 km/s O 3.68 km/s

An argon-40 atom has a mass of 6.64 ✕ 10−26 kg. (a) What temperature (in K) would a gas composed entirely of argon-40 atoms have to be at in order for the rms speed of the atoms to equal the escape speed from Earth, 1.12 ✕ 104 m/s?  K (b) What temperature (in K) would a gas composed entirely of argon-40 atoms have to be at in order for the rms speed of the atoms to equal the escape speed from the Moon, 2.37 ✕ 103 m/s?  K

A research group recently made an interesting discovery, while studying laser interactions with molecular gases. They found that nitrous oxide molecules (mass 44.013 g per mole) can reach temperatures exceeding 1,648 degrees Celsius after a interacting with a few closely-spaced (in time) laser pulses. At this temperature, what is the rms speed (in m/s) of a nitrous oxide molecule?

At what temperature would the rms speed of hydrogen atoms equal the following speeds? (Note: The mass of a hydrogen atom is 1.66 x 10-27 kg.) (a) the escape speed from Earth, 1.12 x 104 m/s K (b) the escape speed from the Moon, 2.37 x 10³ m/s K

Evaluate rms speed, the average kinetic energy of a molecule and total random kinetic energy of all the molecules in 6 moles of air gas at a temperature of 700 K. (Molar mass of air is 28.97 x 10-3 mole/kg, and kB = 1.38 x 10-23 J/K)

Two ideal gases have the same mass density and the same absolute pressure. One of the gases is helium (He), and its temperature is 131 K. The other gas is neon (Ne). What is the temperature of the neon?

A molecule in Earth's atmosphere at 20 °C has a most probable energy      E = kT/2 = 2.02 ×10-21 J     E = kT =4.04 ×10-21 J     E = 3 k T / 2 = 6.1 ×10-21 J     that depends on the mass of the molecule

Dr. Chini's research group recently made an interesting discovery, while studying laser interactions with molecular gases. They found that nitrous oxide molecules (mass 44.013 g per mole) can reach temperatures exceeding 745 degrees Celsius after a interacting with a few closely-spaced (in time) laser pulses. At this temperature, what is the rms speed (in m/s) of a nitrous oxide molecule?
