Why don't all molecules of air move exactly at the same speed?
Molecules of gas all move at the same average speed, if the temperature is held constant. True False Molecules in liquids are, on average, farther away from each other than the molecules in solids. True False The buoyant force on a Styrofoam sphere that is 10% submerged in water is smaller than the buoyant force on a metal sphere that is 100% submerged in water, if the volumes of the two sphere are equal. True False When a truck and...
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 18.99 °C, in m/s?
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.

Calculate the root mean square speed of the oxygen (O_2) molecules in air that is at 24 degree C. m/s
Why don't people move up the social ladder and stay close to their initial status?
At what temperature (in ∘C) do hydrogen molecules have the same rms speed as nitrogen molecules at 100 ∘C?
In order to move in a bigger circle at the same speed, the centripetal force must be: A. Bigger B. Smaller C. The Same D. Zero
By comparing each store's sales and gross profit, why wouldn't all of the stores be exactly the same since each store has access to the same inventory?
