Questions
The temperature of an ideal gas is increased from 120K to 480K.The rms Velocity of the gas molecules is v at 120K.At 480k ,it becomes
a
4v
b
6v
c
8v
d
2v
detailed solution
Correct option is D
Since we know that Vrms=3RTMwWe have, Vrms∝T. ⇒(Vrms)T2=(Vrms)T1T2T1Hence VrmsT2=v×480120=2vTalk to our academic expert!
