Study Notes
Phases of Matter
- Solid: Has a definite volume and shape.
- Liquid: Maintains a definite volume but adapts its shape to the container.
- Gas: Lacks both a definite volume and shape, expanding to fill its container.
- Bose-Einstein Condensate: Formed at temperatures near absolute zero, resulting in super cold and unexcited atoms.
- Plasma: A gas-like state composed of free electrons and ionized atoms; it's the most prevalent phase in the universe, primarily found in stars.
Phase Changes
- Melting: Transition from solid to liquid, occurring at the melting point, which for ice is 0°C.
- Freezing: Process of changing from liquid to solid, at the freezing point, with water also freezing at 0°C.
- Vaporization: Change from liquid to gas, happening at the boiling point.
- Evaporation: Surface molecules of a liquid transitioning to a gas at temperatures below boiling point.
- Boiling: Occurs when molecules beneath a liquid's surface convert to gas.
- Boiling Point: Specific temperature where a liquid transforms into gas; water boils at 100°C.
- Condensation: Change from gas to liquid, often associated with cooling.
- Sublimation: Direct transition from solid to gas without passing through a liquid state.
- Deposition: Reverse of sublimation, where a gas transforms directly into a solid.
Phase Change Mechanisms
- Phase Change Diagram: Visual representation showing the relationship between heat energy and temperature, indicating conditions for phase equilibrium and coexistence.
- Deionization: Transition from plasma to gas, facilitated by the addition or removal of electrons.
- Ionization: Process where a gas converts to plasma via electron addition or removal, creating charged ions.
Properties of Matter
- Heat (Thermal Energy): Energy produced by atomic or molecular motion, affecting the state of matter.
- Viscosity: Measures a liquid's resistance to flow; high viscosity examples include honey and corn syrup.
- Crystal: Solid with particles arranged in a regular, repeating pattern.
- Amorphous Solid: Lacks a rigid particle arrangement, allowing it to flow, e.g., candle wax and glass.
Heat Transfer Mechanisms
- Conduction: Heat transfer via molecular collisions in solids.
- Convection: Heat movement in fluids due to density differences, causing circulation or convection currents.
Thermodynamic Reactions
- Endothermic: Reactions that absorb heat energy from their surroundings.
- Exothermic: Reactions that release heat energy, warming the environment.
