If we believed that the molecules of a gas move around fairly rapidly, we can use this to explain all of the following EXCEPT

why adding more gas increases the pressure.

why most of the volume of the gas sample is taken up by the gas molecules.

why the gas molecules do not settle out on the bottom of the container.

why gas pressure rises with increasing temperature.

The answers are confusing to me in light of the question; therefore, I've chosen to steer clear.
why most of the volume of the gas sample is taken up by the gas molecules.

Since gases are easily compressed, it follows that most of the volume of the gas sample would be empty space. There is a lot of space between the molecules.
