The new volume of occupied by helium gas when its pressure is increased from 760 mm Hg to 950 mm Hg at an initial volume of 5 L is equal to 4 L.
Boyle's Law
Boyle's law state that at constant temperature, the volume of a fixed mass of gas is directly proportional to its pressure.
To calculate the volume of the helium gas, we use the formula below.
Formula:
P₁V₁ = P₂V₂............. Equation 1
Where:
- P₁ = Initial pressure
- V₁ = Initial volume
- P₂ = Final pressure
- V₂ = Final volume.
Make V₂ The subject of the equation
- V₂ = P₁V₁/P₂............... Equation 2
From the question,
Given:
- P₁ = 760 mm Hg
- V₁ = 5 L
- P₂ = 950 mm Hg
Substitute these values into equation 2
- V₂ = (760×5)/950
- V₂ = 4 L.
Hence, The new volume of occupied by helium gas when its pressure is increased from 760 mm Hg to 950 mm Hg at an initial volume of 5 L is equal to 4 L.
