Kinetic Theory and Changes of State [IB Physics SL/HL]

Показать описание

This video gives an overview of the kinetic theory of matter from Theme B of the IB Physics SL & HL course. The particle model is used to explain the microscopic and macroscopic properties of solids, liquids, and gases. It then discusses changes in internal energy that occur as a substance is heated and undergoes changes of phase. Finally, the video introduces heating and cooling curves and relates their features to the energy changes taking place.
