Phase Changes and Their Processes

Emily from the University of Memphis explains phase changes between solids, liquids, and gases. The video covers melting, freezing, evaporation, condensation, sublimation, and deposition, providing examples and scientific terms for each process. The video concludes with a review of the concepts learned.
