Unit 3: Intermolecular Forces and Properties

According to the College Board, "Transformations of matter can be observed in ways that are generally categorized as either a chemical or physical change. The shapes of the particles involved and the space between them are key factors in determining the nature of physical changes.

Solids, Liquids, and Gases

Let's take a step back and remind ourselves a few things about solids, liquids, and gases.

Intermolecular Forces, IMFs, are attractions between entire molecules due to charge differences➕➖. (They typically tend to only affect the solid and liquid phases). Not only are IMFs weaker than bonds-attractive forces due to simultaneous attraction for electrons that exist between 2 nuclei- but they also depend on the type of particle in a sample of matter⚛️.

3.1 Intermolecular Forces

So far, we learned about ionic solids, metallic solids, and alloys. Here's some more you should know!

3.2 Properties of Solids

Let’s look over some of the characteristic properties of the states of matter:

3.3 Solids, Liquids, and Gases

Gases exert pressure on its surroundings. The key phrase you want to associate with pressure is "the number of times particles hit the walls of the container." If you are ever asked to explain any of the relationships in this key topic, always mention that phrase if pressure is involved!

3.4 The Ideal Gas Law

The Kinetic Molecular Theory describes the behavior of ideal gases♨️.

3.5 The Kinetic Molecular Theory of Gases

5 min read

In the real world, gases don’t always behave as defined by the Kinetic Molecular Theory. Conditions of high pressure and low temperature will cause gases to deviate from ideal gas behavior for the following reasons:

3.6 Deviations from the Ideal Gas Law

Solids and liquids are frequently combined to make solutions.

3.7 Mixtures and Solutions

Interactions between solvents and solutes can be represented with particle/molecule diagrams.

3.8 Representations of Solutions

When dealing with solutions, you will have a solute (or multiple solutes) dissolved in a solvent. Many times, a chemist will need to separate these solutions, especially after a chemical reaction has taken place.

3.9 Separation of Solids/Mixtures

The amount of solute needed to form a saturated solution at any particular temperature is the solubility of that solute at that temperature🌡️.

3.10 Solubility and Solubility Rules

Scientists began to understand light and the way light works by analyzing light that was emitted or absorbed by substances.

3.12 Quantum Mechanics and the Photoelectric Effect

In chemistry, many times we want to calculate how light reacts to a certain colored solution with solute in it. Well, spectrophotometry can do just that!
