Boyle's Law
A movable piston encloses 0.78 m³ of gas in a cylinder. The piston is then
pushed downward, changing the volume of the gas to 0.36 m³ and the
pressure to 2.8 kPa. What was the original pressure of the gas?
1. Read and Understand
What information are you given?
initial volume of the piston = V₁ = 0.78 m³
final volume of the piston = V₂ = 0.36 m³
final pressure of the piston = P2 = 2.8 kPa
2. Plan and Solve
What unknown are you trying to calculate?
original pressure of the piston = P₁
What mathematical equation can you use to calculate the unknown?
Boyle's law: P₁V₁= P₂V₂
Rearrange the equation to solve for the unknown variable.
P₂V₂
P₁₂₁=
Substitute the values you know into the equation.
(2.8 kPa) (0.36 m³)
0.78 m³
P₁ =

3. Look Back and Check
Is your answer reasonable?
Yes, the final pressure, 2.8 kPa, is about twice the original pressure, 1.3 kPa.
