PHASES study for quiz!
Download as PPTX, PDF1 like106 views
This document contains definitions and questions related to phase changes, intermolecular forces, heat of fusion/vaporization, and carbon dioxide phase diagrams. Key terms defined include evaporation, sublimation, freezing, melting, condensation, average kinetic energy of particles, heat of fusion of water, heat of vaporization of water, and hydrogen bonding. Questions ask about identifying phases on a carbon dioxide phase diagram, calculating heat required for phase changes of ice and water, and defining intermolecular forces such as hydrogen bonding and viscosity.
