Molecules in a sample of a gas move at a variety of speeds. Molecular speed can be described by the root-mean-square speed of the gas, which is the square root of the average of the squares of the speeds of all the gas molecules. What is the rms speed of a sample of O2 at 12.49 °C, in m/s? A typed answer is prefered. Answer should be in significant figures.

1.Effusion is a process in which a gas escapes from a container through a small opening into a vacuum. In a pair of experiments, a sample of tetrafluoroethylene, C2F4, effuses at a rate of 4.6 × 10-6 mol/h and an unknown gas effuses at a rate of 4.0×10-6 mol/h. Identify the unknown gas. 2.Molecules in a sample of a gas move at a variety of speeds. Molecular speed can be described by the root-mean-square speed of the gas, which is...

3. For a sample of CO2 at 20 ºC, calculate the most probable molecular speed, mean molecular speed and root-mean-square molecular speed. Assume behavior described by the kinetic theory of gases. Also, what would the temperature need to increase to for each of the speeds in part (a) to double? [Hint: Look at the equations! No need for extensive calculations.]

The kinetic theory of gases states that the kinetic energy of a
gas is directly proportional to the temperature of the gas. A
relationship between the microscopic properties of the gas
molecules and the macroscopic properties of the gas can be derived
using the following assumptions: The gas is composed of pointlike
particles separated by comparatively large distances. The gas
molecules are in continual random motion with collisions being
perfectly elastic. The gas molecules exert no long-range forces on
each...
