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?
Yes, at a given temperature, the average kinetic energy per molecule is the same for oxygen and nitrogen molecules in air. This is because the kinetic energy of a gas molecule is determined by its temperature, and not its composition.
Why presence of moisture increases speed of sound in air?
Moisture, in the form of water vapor, increases the speed of sound in air because water molecules are lighter than nitrogen and oxygen molecules present in dry air. This decrease in average molecular weight results in faster sound propagation. Additionally, water vapor has a higher specific heat capacity compared to dry air, which affects the speed of sound as well.
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.
What happens to the spacing between air molecules as they move with greater speed?
As air molecules move with greater speed, they gain kinetic energy, which causes them to collide more frequently and with greater force. This increased motion leads to a greater average distance between the molecules, resulting in a decrease in density. Consequently, in a given volume, the spacing between the molecules becomes larger as their speed increases.
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.
What is the average speed of oxygen molecules in air is about?
The average speed of oxygen molecules in air at room temperature (around 20°C) is approximately 460 meters per second. This speed can vary depending on factors such as temperature and pressure.
What does the experiment suggest about the average speed of hydrogen molecules compared with the average speed of molecules in the air?
The experiment suggests that the average speed of hydrogen molecules is higher than the average speed of molecules in the air. This is because hydrogen molecules are lighter and have a higher root mean square speed due to their lower mass.
What measures the average speed of air molecules?
The temperature of a gas is related to the average kinetic energy of its molecules, which is directly proportional to their speed. Therefore, temperature indirectly measures the average speed of air molecules.
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.
How does the average speed of air molecules relate to the temperature?
The average speed of air molecules increases with temperature. This is because higher temperatures provide more thermal energy to the molecules, causing them to move faster on average. Conversely, lower temperatures result in slower average speeds of air molecules.
Average speed of air molecules?
A thermometer. Temperture is the measure of the kinetic energy, Aka speed, of molecules.
What is the measure for the average speed of air molecules?
The measure for the average speed of air molecules is typically calculated using the root mean square (RMS) speed formula, which considers the distribution of speeds within the gas. The RMS speed provides a representative value that takes into account the kinetic energy of individual molecules in the gas sample.
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?
Yes, at a given temperature, the average kinetic energy per molecule is the same for oxygen and nitrogen molecules in air. This is because the kinetic energy of a gas molecule is determined by its temperature, and not its composition.

Additionally, water vapor has a higher specific heat capacity compared to dry air, which affects the speed of sound as well.
What diffuses faster air or oxygen gas why?
Oxygen gas diffuses faster than air because oxygen molecules are smaller and lighter than the molecules of air, which is mostly composed of nitrogen and oxygen. This allows oxygen molecules to move more quickly through a medium, such as air or other gases.
