This video covers IB Physics subtopic 3.1 from the IB Physics topic 3 syllabus content.

This IB Physics video looks at the components of an object's internal energy, and then how this relates to the kinetic theory. The video further discusses the properties and internal energies of the three main phases of matter. Then, it explores ideal gases and their properties, followed by the introduction of moles, molar mass, and the definition of the pressure of a gas. The three ideal gas laws are then covered, before looking at phase changes and finally distinguishing between the two forms of vaporisation: boiling and evaporation.
