Materials on Earth exist in three main states of matter: solid, liquid, or gas, transitioning between these states alters properties. State changes such as evaporation, boiling, condensation, melting, freezing, sublimation, and deposition maintain constant mass but vary in density.
Insights
- Heating materials can cause state changes by breaking attractive forces between molecules, leading to rearrangements and transitions between solid, liquid, and gas states.
- State changes like evaporation, boiling, condensation, melting, freezing, sublimation, and deposition showcase the various transitions between different states of matter, while maintaining constant mass but varying density.

States of Matter and State Changes
- Materials on Earth exist in three main states of matter: solid, liquid, or gas. State changes occur when a substance transitions between these states, with properties changing accordingly. Heating a material causes attractive forces between molecules to break, leading to rearrangements and state changes.
- State changes include evaporation and boiling (both types of vaporization), where a substance shifts from a liquid to a gas. Condensation is the opposite process, transitioning a gas back to a liquid. Melting and freezing involve transitions between solids and liquids, while sublimation and deposition demonstrate direct shifts between solids and gases. Throughout these changes, the mass of the material remains constant, with only density varying.
