2. A gas is confined in a syringe. When the volume of the cylinder is 750 L the pressure is

150 kPa. What will the volume of the cylinder be when the pressure has risen to 250
kPa?

Answer:

450 L

Step-by-step explanation:

Because you are dealing with pressure and volume, you want to use Boyle's Law to find your missing value. The equation looks like this:

P₁V₁ = P₂V₂

In this equation, "P₁" and "V₁" represent the initial pressure and volume. "P₂" and "V₂" represent the final pressure and temperature. To find the final volume, you can plug the given values into the equation and simplify.

P₁ = 150 pKa P₂ = 250 pKa

V₁ = 750 L V₂ = ? L

P₁V₁ = P₂V₂ <----- Boyle's Law equation

(150 pKa)(750 L) = (250 pKa)V₂ <----- Insert variables

112500 = (250 pKa)V₂ <----- Multiply 150 and 750

450 L = V₂ <----- Divide both sides by 250
