The gas inside of a container exerts #9 Pa# of pressure and is at a temperature of #35 ^o K#. If the temperature of the gas changes to #20 ^oK# with no change in the container's volume, what is the new pressure of the gas?
To solve this problem, we can use the pressure-temperature relationship of gases, illustrated by Gay-Lussac's law:
Let's rearrange this equation to solve for the final pressure,
Plugging in known values, we have
rounded to one significant figure, the lowest amount given in the problem.
