Question

For gaseous state, if most probable speed is denoted by C*, average speed by $\overline{C}$ and mean square speed by C, then for a large number of molecules the ratios of these speeds are :
(a) C* : $\overline{C}$ : C = 1.225 : 1.128 : 1
(b) C* : $\overline{C}$ : C = 1.128 : 1.225 : 1
(c) C* : $\overline{C}$ : C = 1 : 1.128 : 1.225
(d) C* : $\overline{C}$ : C = 1 : 1.225 : 1.128

Answer 1

For gaseous state, if most probable speed is denoted by C*, average speed by $\overline{C}$ and mean square speed by C, then for a large number of molecules the ratios of these speeds are :

(a) C* : $\overline{C}$ : C = 1.225 : 1.128 : 1

(b) C* : $\overline{C}$ : C = 1.128 : 1.225 : 1

(c) C* : $\overline{C}$ : C = 1 : 1.128 : 1.225

(d) C* : $\overline{C}$ : C = 1 : 1.225 : 1.128

Option D..

Hope this helps
