Ch 27: MTTC Integrated Science (Elementary): Gases & Phase Changes

About This Chapter

This chapter's video lessons cover gas and phase changes. Revisit these topics as you prepare to address related questions on the MTTC Integrated Science (Elementary) examination. The chapter also offers short quizzes that test your comprehension of these topics.

MTTC Integrated Science (Elementary): Gases and Phase Changes - Chapter Summary

Go through this chapter to get more information about gases and phase changes before you sit for the MTTC Integrated Science (Elementary) examination. These animated video lessons focus on explaining the kinetic theory of matter, and they'll remind you of the rules for calculating weight and mass. Examples are also provided that outline the process of calculating the volume of gas. Utilize this chapter in order to:

  • Note the contrasts between chemical and physical changes in matter
  • Distinguish between weight and mass
  • Identify the four states of matter
  • Practice using phase diagrams
  • Examine heating curves and phase transitions
  • Recognize the various properties of water
  • Study the periodic table and identify its metals
  • Note the difference between main group elements and transition metals
  • Explore crystal structures
  • Define solvents, solutions and solutes
  • Discuss osmosis and diffusion processes
  • Describe and use the ideal gas law

The video lessons are informative, short and fun. They're designed to provide you with a flexible learning alternative to traditional study as you get ready for the MTTC Integrated Science (Elementary) examination. When you watch the online videos via your computer or tablet, you can utilize the video tags to skip between main topics. The written transcripts offer an alternative review and contain bold terms that can help reinforce your knowledge.

MTTC Integrated Science (Elementary): Gases and Phase Changes - Chapter Objectives

Topics covered in these lessons on gases and phase changes could help you with answering some of the questions in the MTTC Integrated Science (Elementary) examination's physical science content domain. This subarea of the examination makes up 25% of the entire score. Among other topics, this area could test you on your understanding of ideal gas laws and the kinetic theory of matter. You'll have a choice of taking the computer-based test or the paper-based test, both of which include 100 multiple-choice questions. Should you choose the computerized examination, you'll be given up to two hours and 30 minutes for completion. Selecting the paper-based version will give you an expanded time limit of four hours and 30 minutes.

States of Matter and Chemical Versus Physical Changes to Matter

1. States of Matter and Chemical Versus Physical Changes to Matter

The world around us is constantly changing. Chemists put those changes into two main categories: physical changes and chemical changes. This lesson will define and provide examples of each.

Mass and Weight: Differences and Calculations

2. Mass and Weight: Differences and Calculations

We often talk about mass and weight as if they are the same. While they are proportional to each other, they are not, in fact, the same. In this video lesson, you will learn to distinguish between the two, as well as convert one to the other.

The Kinetic Theory of Matter: Definition & The Four States of Matter

3. The Kinetic Theory of Matter: Definition & The Four States of Matter

Everything on Earth is made of matter, but that matter isn't always the same. Matter can exist in four different phases, and the kinetic theory of matter helps us understand the differences between those phases.

Phase Diagrams: Critical Point, Triple Point and Phase Equilibrium Boundaries

4. 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.

Phase Changes and Heating Curves

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.

Properties of Water

6. Properties of Water

Why does ice float? Why can water rise on its own against gravity in a small tube? Find out how these mysterious properties of water can be explained by hydrogen bonds.

Metals on the Periodic Table: Definition & Reactivity

7. Metals on the Periodic Table: Definition & Reactivity

Look around for a second...how many metallic things can you see? Generally when we think of metals, we think of substances that are shiny and durable; however, they're also in our food and in our bodies. Learn what makes a metal a metal and why metals are special.

Transition Metals vs. Main Group Elements: Properties and Differences

8. Transition Metals vs. Main Group Elements: Properties and Differences

Which is better: to be steadfast and consistent or to be a colorful chameleon? This lesson compares and contrasts the main group elements and the transition metals. Then make your own decision!

Crystal Structures and the Unit Cell

9. 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.

Solutions, Solutes, and Solvents

10. Solutions, Solutes, and Solvents

Oh no! Your friend Ben just drank chili oil on a dare, and now his mouth is burning. Should he drink the ice water or vegetable oil to cool his mouth? Quick. Watch this lesson if you aren't sure.

Osmosis, Diffusion and Saturation

11. Osmosis, Diffusion and Saturation

The cells in our bodies are in constant flux through the processes of osmosis and diffusion. Learn about how saturation levels force change, and why we're lucky they do.

The Ideal Gas Law and the Gas Constant

12. The Ideal Gas Law and the Gas Constant

Have you ever wondered why the pressure in your car's tires is higher after you have been driving a while? In this lesson, we are going to discuss the law that governs ideal gases and is used to predict the behavior of real gases: the ideal gas law.

Using the Ideal Gas Law: Calculate Pressure, Volume, Temperature, or Quantity of a Gas

13. Using the Ideal Gas Law: Calculate Pressure, Volume, Temperature, or Quantity of a Gas

In another lesson, you learned that the ideal gas law is expressed as PV = nRT. In this video lesson, we'll go one step further, examining how to rearrange the equation to solve for a missing variable when the others are known.
