Representing solids, liquids, and gases using particulate models
And these are two dimensional particulate models which are simple ways of imagining what is going on at a molecular scale inside of matter. And so you can imagine each of these circles to, depending on what we're dealing with, it's either an ion, it's a molecule, or it's an atom.

PV diagrams - Khan Academy
There are three types of thermodynamic processes you should know: isothermal, isometric, and adiabatic. An isothermal process is all about keeping the temperature constant, while an isometric process maintains a constant volume. The trickiest of the three is the adiabatic process, where no heat is exchanged and changes in volume can alter both pressure and temperature.
