Question
In a certain sample of gas at 25oC the number of molecules having speeds between 4 km sec-1 and 4.1 km sec-1 is N. If the total number of gas molecules at the same temperature are doubled what will happen ?
Options
A.Value of most probable velocity will change
B.Area under the Maxwell′s curve for distribution of speeds will increase by four times
C.No. of molecules between 4 km sec-1 and 4.1 km sec-1 will become 2N
D.No. of molecules between 4 km sec-1 and 4.1 km sec-1 will remain same.
Solution
With increase in temperature, most probable velocity increases & fraction of molecules with velocity equal to M.P. velocity decreases. Total no. of molecules remain same.
