A certain gas is taken to the five states representes by dots in the graph. The plotted lines are isotherms. Order of the most probable speed `v_(p)` of the molecules at these five states is

D. insufficient information to predict the resul

Answer

A

Explanation

Stages 1 and 2 are at the same temperature . Also stages 4 and 5 are at same temperature .
As `V_(p)` is more at higher temperature and same at all stages at equal temperature .
`therefore V_(p_(3)) gt V_(p_(1))= V_(p_(2)) gt V_(p_(4)) = V_(p_(5))`
