Thermal Properties and Heat Transfer

The video reviews key concepts for a physical science final exam, focusing on temperature as a measure of kinetic energy, the transfer of thermal energy through conduction, convection, and radiation, and the Kelvin temperature scale. It also covers specific heat, phase changes, and the laws of thermodynamics. Additionally, it discusses the properties of matter, including atoms, elements, and mixtures.
