When more gas particles enter a container, there is less space for the particles to spread out, and they become compressed. The particles exert more force on the interior volume of the container.

They continue to spread to any space that is available. This means that in contrast to liquids and solids, the volume of a gas is not fixed. Robert Boyle, a chemist and physicist from the 17th ...

This step looks at the behaviour of a fixed quantity of gas under varying pressure, volume and temperature. The kinetic theory model can be used to explain the properties of solids, liquids and ...

The liquid state of matter is an intermediate phase between solid and gas ... so they are not fixed in position. The attraction between the particles in a liquid keeps the volume of the liquid ...

As the volume of the cell increases, so does the maximum possible pathlength with some overlap between each of the different models. For example, a pathlength of approximately 2 m (2.1 m for T10) is ...
