If #9 L# of a gas at room temperature exerts a pressure of #12 kPa# on its container, what pressure will the gas exert if the container's volume changes to #4 L#?
Let's identify our knowns and unknowns:
We can ascertain the answer using Boyle's Law:
Rearrange the equation to solve for
We do this by dividing both sides by
Now all we have to do is plug in the given values:
