About This Chapter
Kinetic Molecular Theory - Chapter Summary
Our interesting chapter covers kinetic molecular theory. These bite-sized lessons present facts pertaining to the different states of matter and the kinetic molecular theory. Studying this chapter should prepare you to do the following:
- Outline the properties of gases associated with the kinetic molecular theory
- Discuss the ideal gas law and the gas constant
- Calculate pressure, temperature, volume and quantity of a gas using the ideal gas law
- Differentiate between ideal gas and plasma
- Compare heat and temperature
- Explain heating curves and phase changes
- Predict the entropy of chemical and physical changes
- Graph and give examples of cyclic processes
We've created this chapter, and all our learning materials, to give you a convenient way to learn or review these subjects. Our lessons are compact and accompanied by self-assessment quizzes to help you build your confidence as you move through the chapter.

1. States of Matter: Solids, Liquids, Gases & Plasma
Learn the four states of matter in the universe: solid, liquid, gas and plasma. Learn about the differences in shape and volume among the four states, which of the states is the most common and why plasma conducts electricity.
2. The Kinetic Molecular Theory: Properties of Gases
What makes a gas ideal? What types of characteristics do ideal gases have? In this lesson, we will discuss the many characteristics of gases and how knowing the microscopic properties of gas particles will help you understand the macroscopic properties of a gas.
3. 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.
4. 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.
5. Differences Between Plasma & Ideal Gas
In this lesson we will describe both ideal and non-ideal gases. We then introduce plasmas, which are similar to non-ideal gases in that they exhibit substantial interactions between particles.
6. Comparing Heat & Temperature
Heat and temperature aren't the same thing, contrary to everyday usage. Learn about the differences between the two concepts in science. Test your understanding with a quiz.
7. 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.
8. Predicting the Entropy of Physical and Chemical Changes
Ever wonder why your bedroom always ends up a mess within hours of you tidying up? That is the magic of entropy. In this lesson, you'll learn why disorder is the natural state of matter and how we can predict entropy change in a physical or chemical reaction.
