The Earth’s atmosphere consists primarily of oxygen (21%) and nitrogen (78%). The rms speed of oxygen molecules (O2) in the atmosphere at a certain location is 535 m/s. (a) What is the temperature of the atmosphere at this location? (b) Would the rms speed of nitrogen molecules (N2) at this location be higher, equal to, or lower than 535 m/s? Explain. (c) Determine the rms speed of N2 at his location.

A krypton-84 atom has a mass of 1.39 x 10-25 kg. (a) What temperature (in K) would a gas composed entirely of krypton-84 atoms have to be at in order for the rms speed of the atoms to equal the escape speed from Earth, 1.12 x 10 m/s? K (b) What temperature (in K) would a gas composed entirely of krypton-84 atoms have to be at in order for the rms speed of the atoms to equal the escape speed from the Moon, 2.37 x 10 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?

1) Calculate the correct values of both the questions.

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?
