If the density of oxygen is 1.44 `kg//m^(3)` at pressure of `10^(5)N//m^(2)`, then the root-mean-square velocity of oxygen molecules in m/s will beA. 469B. 456C. 120D. 270

If the density of oxygen is 1.44 `kg//m^(3)` at pressure of `10^(5)N//

1.	If the density of oxygen is 1.44 `kg//m^(3)` at pressure of `10^(5)N//m^(2)`, then the root-mean-square velocity of oxygen molecules in m/s will beA. 469B. 456C. 120D. 270
Answer» Correct Answer - B `C=sqrt((3P)/(rho))=sqrt((3xx10^(5))/(1.44))=(1.732xx3.13xx10^2)/(1.2)` `=456m//s`.
