### About This Chapter

## MTEL Middle School Math/ Science: Phase Changes for Liquids & Solids - Chapter Summary

Liquids and solids will shift back and forth during many chemical processes. This chapter of the MTEL Middle School Math/ Science course arms you with a study guide that walks you through the material that you will find on the exam. Video lessons included in this section of the course will act as a fun alternative to a traditional book and will cover the following topics:

- The kinetic molecular theory and properties
- Critical and triple points
- The different stages of phase changes
- Differences in phase diagrams
- Crystal structures and unit cells

This collection of video lessons is designed to be viewed not only on your home computer but your mobile device as well, so you can squeeze in a study session or two no matter what time of day it is. With a team of experts available at the touch of a button, any additional questions you have regarding the phase change material can be answered.

### MTEL Middle School Math/ Science: Phase Changes for Liquids & Solids - Chapter Objectives

The MTEL Middle School Math/ Science exam is designed for the certification of math and science teachers for elementary schools in the state of Massachusetts. The phase change content can be found inside the Chemistry section of the multiple-choice test, and this section occupies about eight percent of the total exam.

### 1. The Kinetic Molecular Theory: Properties of Solids and Liquids

This lesson explores the kinetic molecular theory and how it pertains to the properties of solids and liquids. You'll learn the properties of solids and liquids, discover the types of intermolecular attractions that occur between them and gain an understanding how phase changes happen.

### 2. Phase Diagrams: Critical Point, Triple Point and Phase Equilibrium Boundaries

Learn what a phase diagram is and how to interpret phase diagrams. Discover how to use a phase diagram to locate the phase equilibrium boundaries. Also, learn what a triple point and critical point are and how to locate them on a phase diagram.

### 3. Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition

Substances on Earth can exist in one of four phases, but mostly, they exist in one of three: solid, liquid or gas. Learn the six changes of phase: freezing, melting, condensation, vaporization, sublimation and deposition.

### 4. Phase Diagram of Water vs Other Substances: Differences & Meaning

Phase diagrams give scientists specific information about how phase changes occur at different pressures and temperatures. This lesson examines phase diagrams, focusing on water and how it's a little different from most other substances.

### 5. Phase Changes and Heating Curves

Learn the phases - gas, liquid, solid and plasma. Learn what a phase diagram is and what terms describe the movement between phases: melting, sublimating, freezing, vaporization, condensation, and deposition. Discover why heating curves have plateaus, what a phase transition is, and what happens during this transition.

### 6. Crystal Structures and the Unit Cell

This crystallography lesson explores the structure and properties of crystals. You'll learn about the parts of a crystal structure, types of crystals and patterns created by unit cells.
