Question
Graph shows a hypothetical speed distribution for a sample of N gas particle (for V > V0; 
= 0)
= 0)Options
A.The value of aV0 is 2N.
B.The ratio Vavg/V0 is equal to 2/3.
C.The ratio Vrms/V0 is equal to 1/√2.
D.Three fourth of the total particle has a speed between 0.5 V0 and V0.
Solution
Area under the curve is equal to number of molecules of the gas sample. Hence
N =
. a . V0 ⇒ aV0 = 2N
Vavg =
V0 ⇒ 
vrms2 =
⇒ 
Area under the curve from 0.5 V0 to V0 is
of total area.
N =
. a . V0 ⇒ aV0 = 2NVavg =
V0 ⇒ vrms2 =
⇒ Area under the curve from 0.5 V0 to V0 is
of total area.Create a free account to view solution
