(chatquestion)...16. Initially the volume of an ideal gas (y = 1.5) is v at which root mean square velocity of the molecules is V, If root mean square velocity is reduced so that ratio of two root mean square velocities (initial to final ) is r and corresponding ratio of volumes (final to initial volume) is V,, then (a) V, =(r)* (b) V, = (r)' (c) V, = (r)' (d) V, =r
