What is their average speed?
What is their root mean square (rms) speed?
Typical root-mean-square speeds of molecules in gases are large, even at low temperatures. Find the root-mean-square speed for helium atoms at a temperature of 5.00 K.
Find the temperature at which the average speed of carbon dioxide molecules is 510 m/s. Use a value of 44.0 g/mol for the molar mass of carbon dioxide.
