The root mean square velocity of a gas particle is equal to the square root of (3RT/M), where R is the gas constant (in J K^-1 mol^-1), T is temperature in Kelvin (around 293 at room temperature) and M is molar mass (0.028 kg/mol for diatomic nitrogen, which makes up >50% of the atmosphere. Plugging in these values gives approximately 511 m/s.

∙ 13y agoTemperature is not a factor for the speed of light. Speed of light in air is essentially the same as speed of light in a vacuum therefore being approximately 3*10^8

∙ 11y agowondering if anyone knew the speed of light in still air. if it's hmwk just do a normal one.

How fast are molecules in the air moving?
Temperature has a big effect on how fast air molecules travel. Air molecules move faster in hot weather and they move slower in cold weather.
Why do the air molecules inside a bicycle tire speed up as the temperature gets warmer?
because the heat is transferred to the molecules and gives them more kinetic energy
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.
How are the speeds of molecules of air affected when the air is compressed by the action of a tire pump?
When air is pumped into a tire at great speed, there is an increase in the temperature of the air. This is because the fast compressions cause the air molecules to move, whereas they remain still during a slow compression.
Is there a speed of smell?
It will be 332 m/s because it is the speed of air & smell comes with the air molecules.
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.
Average speed of air molecules?
A thermometer. Temperture is the measure of the kinetic energy, Aka speed, of molecules.
How fast are molecules in the air moving?
Temperature has a big effect on how fast air molecules travel. Air molecules move faster in hot weather and they move slower in cold weather.
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.
When a liquid is at room temperature a few molecules escape into the air by what?
vaporization
Why does the speed of sound depend on air temperature?
Temperature is a condition that affects the speed of sound. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly. The speed of sound in room temperature air is 346 meters per second. This is faster than 331 meters per second, which is the speed of sound in air at freezing temperatures. The formula to find the speed of sound in air is as follows: v = 331m/s + 0.6m/s/C * T v is the speed of sound and T is the temperature of the air.
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 did Isaac Newton calculate the speed of sound in air at room temperature to be?
768mph
What is the speed of sound traveling through the air at room temperature?
In dry air, at 20°C, the speed of sound is 343 meters/second.
What is the relationship between water vapor air molecules temperature?
Whatever it is, gas, vapor, liquid, solid - the higher the temperature, the higher is the local agitation/speed of the molecules/atoms.
What is the relationship between temperature air molecules and water vapor?
Whatever it is, gas, vapor, liquid, solid - the higher the temperature, the higher is the local agitation/speed of the molecules/atoms.
When you put cool water in the glass why the outside vapour appears?
as the air molecules are free to move , when we pour cold water in glass its surface become cooler than the room temperature , thr air molecules stick with the walls of glass and due to low temperature there these air molecules deposit there.
