Question

An unknown gas having density 4 k g m - 3 and pressure 1.2 × 1 0 5 N m - 2 . The ratio of root mean square and most probable velocity is, 1, 1.22, 1.12, Data are not sufficient

MARKS App · Accepted Answer

Ratio of v r m s and v m p is approx 1.22 at any pressure and given density v r m s = 3 P d = 300 m s e c - 1 v mp = 2 P d = 245 m sec − 1 v r m s v m p = 1.22
