Measures how fast air molecules are moving?
A thermometer. Temperture is the measure of the kinetic energy, Aka speed, of molecules.
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 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
Would sound travel faster in warm air or cold air why?
The sound travel faster in warm air because the average mean speed of the molecules of air is faster in warm air than on cool air. Sound is transferred by collisions of molecules. Therefore sound waves will travel faster on warm air because collisions of molecules of air in warm air is greater.
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.
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.

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.
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 measures of the force with which air molecules push on a surface?
air pressureair presureAir Pressure
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
Is radiation the instrument used to measure wind speed?
No, a barometer measures air pressure. Though wind is caused by variances in air pressure the direct measurement of wind is done by an anemometeryes
