Questions
The ratio of rms speed of an ideal gas molecules at pressure p to that at pressure 2p at const volume is
a
1 : 2
b
2 : 1
c
1 : 2
d
2 : 1
detailed solution
Correct option is C
According to the question,In the first condition, p = 13ρvrms2 …(i)In the second condition, 2p=13ρvrms' …(ii)On dividing Eq. (i) by Eq. (ii), we get vrms2vrms'2=12⇒vrmsvrms'=12Talk to our academic expert!
