Question

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:

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

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

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

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