The density of a gas is `6xx 10^(-2 )kg//m^(3)` and the root mean square velocity of the gas molecules is 500 m/s. The pressure exerted by the gas on the walls of the vessel is

Options

A. `5xx10^(3)N//m^(2)`
B. `1.2xx10^(4)N//m^(2)`
C. `30N//m^(2)`
D. `0.8xx10^(4)N//m^(2)`

Answer

A

Explanation

`P=(1)/(3) rho C^(2)=(1)/(3)xx6xx10^(-2)xx500xx500`
`=5xx10^(3)N//m^(2)`.
