States of Matter: Solids, Liquids, Gases, & Plasma

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.

The Kinetic Molecular Theory: Properties of Gases

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.

The Ideal Gas Law and the Gas Constant

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.

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

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.

Differences Between Plasma & Ideal Gas

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.

Comparing Heat & Temperature

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.

Phase Changes and Heating Curves

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.

Predicting the Entropy of Physical and Chemical Changes

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.
