IFAP - Module Overview

Intermolecular Forces and Properties

Introduction

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. The properties of solids, liquids, and gases reflect the relative orderliness of the arrangement of particles in those states, their relative freedom of motion, and the nature and strength of the interactions between them. There is a relationship between the macroscopic properties of solids, liquids, and gases, as well as the structure of the constituent particles of those materials on the molecular and atomic scale.

You will draw upon your understanding of molecular geometry and polarity from the previous module to understand the forces between molecules. In the gas phase, you will explore the variables that influence the behavior of matter in calculations and with models with gas law calculations. The behavior of matter in solution and mixtures will also be part of this module. The factors that influence the dissolution process and calculations related to aqueous solutions quantify the concepts along with the theoretical models and behaviors explored. 

Module Lessons Preview

In this module, we will study the following topics:

Intermolecular Forces: How forces between molecules account for the physical properties of matter.

Properties of Solids and Liquids: The uniqueness of solids and liquid materials in chemistry terms.

Properties and Calculations with Gases: Much of chemical understanding started with the historical study of gases.

Kinetic Molecular Theory: Modern chemical theories that help describe the behavior of matter.

Solutions and Mixtures: Chemistry of materials when found in solution.

Molarity: Quantitative study of concentration of solutions

Solubility: Quantitative analysis of how much solvent it takes to keep a solute dissolved.

Separating Mixtures: Physically breaking apart solutions into pure substances.
