If the R.M.S. velocity of oxygen molecul...

If the R.M.S. velocity of oxygen molecules at NTP is 460 m/s, then the R.M.S. velocity at `127^(@)C` will be

A

556.6 m/s

B

55.66 m/s

C

380 m/s

D

382 m/s

Text Solution

Verified by Experts

The correct Answer is:
A
`(C_(2))/(C_(1))=sqrt((T_(2))/(T_(1)))=sqrt((400)/(127))=(20)/(sqrt(127))`
`C_(2)=(460xx20)/(sqrt(127))=556.6m//s`.
