Question
A certain gas is taken to the five states represented by dots in the graph. The plotted lines are isotherms. Order of the most probable speed vp of the molecules at these five states is :
Options
A.VP at 3 > VP at 1 = VP at 2 > VP at 4 = VP at 5
B.VP at 1 > VP at 2 = VP at 3 > VP at 4 > VP at 5
C.VP at 3 > VP at 2 = VP at 4 > VP at 1 > VP at 5
D.Insufficient information to predict the result.
Solution
Stages 1 and 2 are at same temperature also stages 4 and 5 are at same temperature.
As, VP is more at higher temperature and same at all stages at equal temperature.
∴ VP3 > VP1 = VP2 > VP4 = VP5 (As T3 > T2 = T1 > T4 = T5)
As, VP is more at higher temperature and same at all stages at equal temperature.
∴ VP3 > VP1 = VP2 > VP4 = VP5 (As T3 > T2 = T1 > T4 = T5)
