If #8 L# of a gas at room temperature exerts a pressure of #28 kPa# on its container, what pressure will the gas exert if the container's volume changes to #9 L#?
The final pressure will be 25 kPa.
This is an example of Boyle's law, which states that the volume of a gas kept at constant temperature varies inversely with the volume. This means that when volume increases, pressure decreases. The equation required to solve this problem is
Rearrange the equation to isolate
