Given below are two statements :
Statement I : The average momentum of a molecule in a sample of an ideal gas depends on temperature.
Statement II : The rms speed of oxygen molecules in a gas is $\displaystyle v$. If the temperature is doubled and the oxygen molecules dissociate into oxygen atoms, the rms speed will become $\displaystyle 2 v$.
In the light of the above statements, choose the correct answer from the options given below :
Official answer
(4)
Statement I is false but Statement II is true
