The volume of a gas varies inversely as the pressure on it. If the volume is 240 cm3 under a pressure of 30 kg/cm2, what pressure has to be applied to have a volume of 160 cm3

Given,

The volume of a gas varies inversely as the pressure on it. If the volume is 240 cm³ under a pressure of 30 kg/cm².

To find,

What pressure has to be applied to have a volume of 160 cm³.

Solution,

ATQ,

Volume of a gas is inversely proportional to the pressure. Mathematically,

or

We have, V₁ = 240 cm³, V₂ = 160 cm³, P₁ = 30 km/cm², P₂=?

So, the new pressure is .

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
