Problem

For gaseous state, if most probable speed is denoted by

C^*

, average speed by

\bar{C}

and mean square speed by

C

, then for a large number of molecules the ratios of these speeds are : [JEE (Main) 2013] (1)

C^* : \bar{C} : C = 1 : 1.128 : 1.225

(2)

C^* : \bar{C} : C = 1 : 1.225 : 1.128

(3)

C^* : \bar{C} : C = 1.225 : 1.128 : 1

(4)

C^* : \bar{C} : C = 1.128 : 1.225 : 1
