Definition
Phase diagrams in Chemistry represent the states of matter (solid, liquid, gas) of a substance at different pressures and temperatures. They show how state transitions occur, such as melting, boiling, and sublimation, providing a visual guide to understand the behavior of substances under varying conditions.
