Study Notes
Chemistry Overview
- Chemistry investigates matter and its transformations.
- Comprised of five major branches:
- Organic: Carbon-containing compounds.
- Inorganic: Compounds not primarily based on carbon.
- Analytical: Measurement of material properties.
- Physical: Intersection of physics and chemical principles.
- Biochemistry: Chemical processes within living organisms.
Understanding Matter
- Matter is defined as anything with mass and volume.
- Composed of atoms; examples include protons, currency, and flowers.
- Non-examples include intangible entities like light and heat.
States of Matter
-
Solid:
- Particles arranged in a fixed, orderly pattern; closely packed.
- High density, incompressible, fixed shape, and incapable of flowing.
-
Liquid:
- Particles closely packed but with a random arrangement; can move past one another.
- Shape can change, volume remains constant, and can flow easily despite being incompressible.
-
Gas:
- Particles are widely spaced and move freely in various directions.
- Low density, easily compressible, and expand to fill the entire container.
Classification of Matter
- Divided into:
- Pure Substances: Elements or compounds.
- Mixtures: Homogeneous (uniform composition) or heterogeneous (distinct, separate components).
Changes of State
- Transitions between states of matter include:
- Melting: Solid to Liquid.
- Freezing: Liquid to Solid.
- Evaporation/Boiling: Liquid to Gas.
- Condensation: Gas to Liquid.
- Sublimation: Solid to Gas.
- Deposition: Gas to Solid.
Separation Techniques
- Filtration: Separating solid from liquid using a filter.
- Crystallization: Formation of pure solid particles from a solution.
- Simple Distillation: Separation based on boiling points by heating a mixture.
