The answer is about 478 meters per second, which you can convert to about 1720 km/hr
V = sqrt(3*R*T/M), where R is Boltzmann's constant (8.31 J/mol-K), T is temperature in Kelvin (use 293K for room temp and M is the mass of one mole of oxygen in kilograms (.032 kg)

Is the average kinetic energy per molecule the same for oxygen and nitrogen molecules in air at a given temperature?
Oxygen and nitrogen have equal average kinetic energy per molecule at room temperature. This is assuming that both oxygen and nitrogen molecules are in fact at room temperature.
What effect does the obsence of heat have on air molecules?
When heat touches air molecules they speed up but when cold air touches molecules they slow down.
As the density of air decreases its pressure what?
Temperature is always measured when surface have transition from hot to cold or vice-versa. When molecules decrease in density, implies the individual molecules get cooler/hotter faster to room temp.hence,When air molecules decrease air temperature rapidly changes to room temperature or ambient temperature.
How does the distance between the particles in atmospheric air compare to the size of the particles themselves?
Usually in a gas, the distance between molecules is larger.
How fast is air molecules if temperature of the gas is 0 Celsius degrees?
The air molecules would go very slow because the air molecules are tight close together.
Temperature measures the blank in the air?
The temperature of the air is a measure of the degree of molecular movement of all the Nitrogen and Oxygen molecules that largely make up air. Technically, it is determined by getting the average speed of a body's molecules.
What measures the average speed of air molecules?
WUB
Average speed of air molecules?
A thermometer. Temperture is the measure of the kinetic energy, Aka speed, of molecules.
Why would you not expect all of the molecules of air in your room to have the same average speed?
They do have the same average speed ... it's called the air temprature. I believe you need to define average for yourself.
do bromine molecules move faster then air molecules?
The speed of gas molecules is primarily determined by their temperature, not their specific identity. At the same temperature, bromine molecules and air molecules would have similar average speeds.
How many out of 200 air molecules are oxygen?
Air is 21% oxygen so 21% of 200 is 42 oxygen molecules.
Is the average kinetic energy per molecule the same for oxygen and nitrogen molecules in air at a given temperature?
Oxygen and nitrogen have equal average kinetic energy per molecule at room temperature. This is assuming that both oxygen and nitrogen molecules are in fact at room temperature.
What air molecules?
air molecules are , nitrogen , oxygen, and carbon dioxide mosly nitrogen (75%)
The different molecules that make up the air in a room have on average the same kinetic energy how does the speed of the different air molecules depend on their masses?
If mixed together, molecules with various masses will move at different speeds related to their mass.
What happens when warm air molecules move farther apart?
When air warms the molecules on average move more quickly. If the volume occupied remains the same then the average distance apart remains the same, if the pressure remains the same the air will expand and this means that the air molecules will get farther apart.
What effect does the obsence of heat have on air molecules?
When heat touches air molecules they speed up but when cold air touches molecules they slow down.
What is the average speed in meters per second at 20 degrees Celsius the average velocity of N2 molecules in air is 1050 mph?
469.4 m/s
