1.	Let u_(av), u_(rms)and u_(mp)are average, root means square and most probable speed the molcules in an ideal monoatomic gas at absolute temperature T. The mass of molecule is m, then :
Answer» none of the moelcules can have a speed greater than `sqrt(2)u_(rms)` none of the molecules can have a speed less than `sqrt(2)u_(MP)`. `u_(av) lt u_(rms) lt u_(mp)` the AVERAGE kinetic energy of molecule is `3/4m u_(mp)^2` SOLUTION :`K.E. = 1/2 mU_(rms)^2 = 1/2 m xx 3/2 xx U_(mp)^2 = 3/4 U_(mp)^2`.
