Boyle's Law says that the volume of a gas varies inversely with the pressure. When the volume of a certain gas is 2 L, the pressure is 1165 kPa (kilopascals),What is the volume when the pressure is 466 kPa ?

SOLUTION

The volume of a gas varies inversely with the pressure

This is written as:

[tex]PV=k[/tex]

Where k is a constant

When V=2L, P=1165kPa

Substitute these values into the above equation

[tex]1165\times2=k[/tex]

It follows:

[tex]k=2330[/tex]

Substituting the value of k into the equation gives

[tex]PV=2330[/tex]

Find V when P=466kpa

Substitute P=466 into the equation PV=2330

[tex]466\times V=2330[/tex]

Solve for V

[tex]\begin{gathered} V=\frac{2330}{466} \\ V=5 \end{gathered}[/tex]

Therefore The required volume is 5L
