The Root Mean Square Speed of Nitrogen Molecules in Air $\omicron$

question 70

Short Answer

The root mean square speed of nitrogen molecules in air at 20 ^$\omicron$ C is 511 m/s in a certain container.If the gas is allowed to expand to twice its original volume,
the root mean square velocity of nitrogen molecules drops to 325 m/s .Calculate the temperature after the gas has expanded.
