Question

a container contain a gas 500 molecule per cm3 at 3 Kelvin find pressure​

Answer 1

Explanation:

The pressure at the bottom of the container is therefore equal to atmospheric pressure added to the weight of the fluid divided by the area: p=p0+ρAhgA=p0+ρhg. p = p 0 + ρ A h g A = p 0 + ρ h g . This equation is only good for pressure at a depth for a fluid of constant density.
