Study Notes
The Particle Model of Matter
- The particle model of matter states that all substances are made up of tiny particles that have spaces between them, are always moving, and are attracted to each other.
States of Matter
- Solid: Tightly packed particles with little space between them, resulting in a definite shape and volume. Solid particles move in a fixed position, and are not easily compressed.
- Liquid: Particles have more space between them than solids, allowing for a definite volume but no fixed shape. Liquids flow easily and are not easily compressed.
- Gas: Particles have wide spaces between them and move freely, resulting in no fixed shape and volume. Gases are easily compressible.
Changes of State
- Sublimation: The process where a solid turns directly into a gas or vice versa.
- Melting/Fusion: The process where a solid turns into a liquid.
- Freezing/Solidification: The process where a liquid turns into a solid.
- Condensation: The process where a gas turns into a liquid.
- Vaporization: The process where a liquid turns into a gas.
Pure Substances
- Pure Substance: Contains only one type of particle.
- Element: A pure substance composed of only one type of atom.
- Compound: A pure substance composed of two or more types of atoms.
Mixtures
- Homogeneous Mixture (solution): Appears to be one substance, the components are evenly distributed at a molecular level.
- Heterogeneous Mixture: Two or more parts can be seen.
- Suspension: Parts will settle slowly after mixing.
- Colloid: Cloudy droplets are so small that they don't separate easily.
- Emulsion: A mixture of two liquids that usually do not mix together.
Dissolving
- Dissolving: Forming a solution by mixing two or more materials.
- Soluble: Able to be dissolved.
- Solute: The substance that is dissolved.
- Solvent: The substance in which the solute dissolves.
- Solubility: How much a solute can dissolve in a given amount of solvent at a certain temperature.
- Insoluble: Unable to dissolve.
- Rate of Dissolving: How fast a solute dissolves in a solvent.
- Unsaturated: More of the solute could dissolve in a specific amount of solvent at the same temperature.
- Saturated: No more solute will dissolve in a specific amount of solvent at a specific temperature.
- Supersaturated: A solution with more solute than normally.
- Saturation Point: The point at which no more solute can be dissolved.
Properties of Fluids
- Viscosity: The thickness or thinness of a fluid.
- Flow rate: How fast a fluid flows.
- Buoyancy: The tendency of a material to rise or float in a fluid.
- Neutral Buoyancy: When the force of gravity equals the buoyant force.
- Pressure: Force applied to a given area.
- Compressible: Capable of being squeezed into a smaller volume.
- Incompressible: Not capable of being squeezed into a smaller volume.
Compressed Gas
- Compressed Gas: Gases under pressure.
WHMIS
- WHMIS: Workplace Hazardous Materials Information System.
Hazardous Material Safety
- Hazardous Materials: Substances that can cause death, toxicity (oral, dermal, inhalation), health hazards (cancer, organ damage), and other dangerous effects.
