What will be the r.m.s. speed of a gas at `800^(@)K` ?

A

four times the values at 200 K

B

half the value at 200 K

C

twice the value at 200 K

D

same as at 200 K

Text Solution

Verified by Experts

The correct Answer is:
C

`C_(1)=K sqrt(800) and C_(2) =K sqrt(200)`
`(C_(2))/(C_(1))=sqrt((200)/(800))=(1)/(2) C_(1)=2C_(2)`
