Understanding Specific Latent Heat and Change of State in Substances

The video tutorial explains how energy is absorbed or emitted by a substance during state changes, using a graph to illustrate temperature variations with thermal energy absorption. It covers the concepts of melting and boiling, emphasizing that temperature remains constant during state changes while potential energy increases. The tutorial introduces equations for calculating energy required for state changes, providing examples with water, gold, and hydrogen. It concludes by discussing the types of latent heat: fusion and vaporization.
