Study Notes
- There are three states of matter: solid, liquid, and gas.
- Pure substances have only one type of particle, while mixtures have two or more particles.
- The particle theory has six postulates that explain the behavior of particles.
- Mechanical mixtures have different substances that are not evenly spaced, while solutions have evenly spaced particles.
- Qualitative measurements rely on taste, while quantitative measurements use numbers.
- There are several separation techniques, including evaporation, sifting, filtration, distillation, magnetism, and flotation and settling.
- Industries use separation techniques for filtering sewage and evaporating maple syrup.
- Solids in a mechanical mixture can be separated from each other using sifting or magnetism.
- Filtration is a separation technique that uses strainers to separate particles.
- Distillation involves using heat to collect the condensation of a liquid.
