Perhaps this is more of a physics question, but I got this question wrong on a chemistry test and was wondering if someone here could explain the correct answer to me. I thought that all three would decrease, but that was not an option.
If an ideal gas was cooled at a constant volume in a container, which of the following values would decrease?
I. The pressure exerted by the gas on its container
II. The average distance between gas molecules
III. The average speed of the gas molecules
