The Phases Coldest Hottest Solid Liquid Gas Plasma
Energy during a Phase Change Example) Water Freezes (liquid to solid) at 0oC Stays constant at 0oC during freezing
Energy during a Phase Change Example) Water Melts (solid to liquid) at 0oC Stays constant at 0oC during melting
Energy during a Phase Change Example) Water Boils (liquid to gas) at 100oC Stays constant at 100oC during boiling
Phase Changes • In summary: During a phase change, the temperature is CONSTANT!!!
