Question

The volume of 2mol hydrogen gas at 1 atm pressure and 273 K is 44.8L.

a) Name the scientist who established the relationship between the volume and pressure of

a gas through experiment.

b)What will be the new pressure if the volume hydrogen gas is changed to 22.4L?

( temperature is constant)

c)Suggest a method to increase the volume of this gas without changing the pressure and

mass.​

Answer 1

Given info : The volume of 2 mol hydrogen gas at 1 atm pressure and 273k is 44.8L.

To find :

• a) Name the scientist who established the relationship between the volume and pressure of  a gas through experiment.
• b)What will be the new pressure if the volume hydrogen gas is changed to 22.4L?
• c)Suggest a method to increase the volume of this gas without changing the pressure and  mass.​

solution : (a) volume is inversely proportional to pressure of an ideal gas. it is known as Boyle's law. because it was given by the Robert Boyle.

(b) ∵ PV = constant

∴ P₁V₁ = P₂V₂

⇒ 1 atm × 44.8 L = P₂ × 22.4L

⇒ P₂ = 2 atm.

therefore the new pressure of gas would be 2 atm.

(c) we should use Charle's law, when a gas is taken at constant pressure in a container. it varies with temperature. it is directly proportional to the temperature of gas.

i.e., V ∝ T ,

so we can increase the volume by increasing its temperature.
