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

1. C* : C : C = 1 : 1.128 : 1.225
2. C* : C : C = 1 : 1.225 : 1.128
3. C* : C : C = 1.225 : 1.128 : 1
4. C* : C : C = 1.128 : 1.225 : 1

Correct answer: C* : C : C = 1 : 1.128 : 1.225
