Study Notes
Phase Changes
- Deposition occurs when a gas turns into a solid, skipping the liquid phase.
- Freezing occurs when a liquid loses energy or gains pressure and turns into a solid.
- Condensation occurs when a gas cools into a liquid.
- Evaporation occurs when a liquid turns into a gas.
- Sublimation occurs when a solid turns straight into a gas.
Phase Characteristics
- Solids have atoms and molecules that are closer together, allowing for a definite shape and size.
- Gases have no definite shape, regardless of the container.
Phase Change Concepts
- A phase change is a change in the state of a substance from one phase to another.
- Melting occurs when a solid becomes a liquid, typically when it gains energy or heat.
- The triple point is the temperature and pressure at which a substance can exist in all three phases (solid, liquid, and gas) simultaneously.
Slow Phase Changes
- Evaporation occurs slowly over time when a liquid turns into a gas.
Phase Change Processes
- Sublimation is the process in which a solid skips the liquid stage and phases directly into a gas.
- Condensation occurs when water vapor condenses on dust to create clouds.
Environmental Factors
- The main factor that causes lakes and rivers to freeze in the winter is low temperature.
- Deposition occurs when a gas turns directly into a solid, skipping the liquid stage.
