How Temperature Changes the Properties of Matter

Heat = Motion: Raising temperature makes particles move faster, lowering it slows them down.
Solid Shift: Warm a solid and it may soften, melt, or expand slightly.
Liquid Flow: Heating a liquid makes it flow more easily by reducing viscosity.
Gas Boost: Hotter gases expand and spread, increasing pressure if trapped.
Phase Changes: Temperature changes drive melting, freezing, boiling, and condensation.
Density Drop: Most materials expand when heated, lowering their density.
Conductivity Change: Metals conduct electricity better when cool but lose efficiency when hot.
Color Clues: Heat can make objects glow—like red-hot iron or blue flames.
Everyday Impact: Temperature shifts explain why tires inflate more in summer than winter.
Life Link: From cooking food to keeping engines running, temperature rules matter’s behavior.
