Unit 3: Intermolecular Forces and Properties

- Intermolecular forces can explain the physical properties of a material.
- Matter exists in three states; solids, liquids, and gas, and their differences are influenced by variances in spacing and motion of the molecules.
- Gas properties are explained macroscopically - using the relationships among pressure, volume, temperature, moles, gas constant - and molecularly by the motion of the gas.
- Interactions between intermolecular forces influence the solubility and separation of mixtures.
- Spectroscopy can determine the structure and concentration in a mixture of a chemical species.

- Identify experimental procedures that are aligned to the question.
- Identify or describe potential sources of experimental error.
- Represent visually the relationship between the structures and interactions across multiple levels or scales.
- Explain chemical properties or phenomena using given chemical theories, models, and representations.
- Explain the connection between particulate-level and macroscopic properties of a substance using models and representations.
- Explain the degree to which a model or representation describes the connection between particulate-level properties and macroscopic properties.
- Explain the relationship between variables within an equation when one variable changes.
- Calculate, estimate, or predict an unknown quantities from known quantities by selecting and following a logical computational pathway and attending to precision.
- Providing reasoning to justify a claim using connections between particulate and macroscopic scales or levels.
