Five bicyclists are riding at the following speeds: 5.40 m/s, 5.70 m/s, 5.80 m/s, 6.00 m/s, and 6.50 m/s.
What is their average speed?
What is their root mean square (rms) speed?
Typical root-mean-square speeds of molecules in gasses 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.
The root-mean-square speed of carbon dioxide molecules in a flame is found to be m/s. Find the temperature of the flame. Use a value of 44.0 g/mol for the molar mass of carbon dioxide molecules.
How many times greater is the average translational kinetic energy of a nitrogen molecule at a temperature of 300 K to the gravitational potential energy of a nitrogen-molecule-Earth system at the ceiling of a 3.00-m-tall room with respect to the same system with the molecule at the floor?
