# Temperature at which r.m.s. speed of O2 is equal to that of neon at 300 K is :

Root mean square velocity = $\sqrt{\frac{3RT}{M}}$
It means it is directly proportional to Temperature and inversely proportional to Molar mass.

Temperature at which r.m.s. speed of O2 is equal to that of neon at 300 K is 475.9K
