How did tripling the pressure change the gas volume?

1 answer

According to Boyle's Law, the volume of a gas is inversely proportional to its pressure, assuming the temperature and amount of gas remain constant. This means that if you triple the pressure of a gas, the volume will decrease by a factor of three.

Mathematically, Boyle's Law can be represented as:

P₁V₁ = P₂V₂

where P₁ and V₁ are the initial pressure and volume, and P₂ and V₂ are the final pressure and volume.

If the pressure is tripled (P₂ = 3P₁), the equation becomes:

P₁V₁ = 3P₁V₂

Rearranging the equation to solve for V₂ yields:

V₂ = V₁/3

This shows that the gas volume will decrease to one-third of its initial volume when the pressure is tripled.
