Calculate the root mean square velocity ...

Calculate the root mean square velocity of a gas of density 1.5 g `"litre "^(-1)` at a pressure of `2xx10^6 Nm^(-2)` .

Text Solution

Verified by Experts

`rho=1.5g "litre"^(-1) = 1.5 "kgm"^(-3)`,
`P = 2 xx10^6 Nm^(-2)`
`v_(rms)=sqrt((3P)/rho)`
`=sqrt((3xx2xx10^6)/(1.5))=2xx10^3 ms^(-1)`
