1.	The root mean square speed of the molecules of a diatomic gas is V. When the temperature is doubled ,the molecules dissociate into two atoms. The new root mean square speed of the atom is :
Answer» v 2v `sqrt2v` 4v Solution :`v_(rms)=sqrt((3RT)/M)` According to PROBLEM T will become 2T and M will become `M//2` . So the value of `v_(rms)` will increase by `SQRT4 = 2` TIMES . i.e., NEW root mean square VELOCITY will be 2v.
