    The absolute temperature of a gas is      increased 3 times. The root mean square             velocity of the molecules will become :

    A)  3 times                               

    B)  9 times

    C)  \[\frac{1}{3}\] times                     

    D)  \[\sqrt{3}\] times

    Correct Answer: D

    Solution :

                    rms velocity \[{{\upsilon }_{rms}}\propto \sqrt{T}\] if temperature is increased to 3 times/then rms velocity will become \[\sqrt{3}\] times.
