Pressure: Definition, Units, and Conversions

1. Pressure: Definition, Units, and Conversions

Have you ever wondered what pressure is and how it gets measured? In this lesson, we are going to define pressure and explain some of the units that are used to express measurements of pressure.

What is Temperature? - Definition & Measurement

2. What is Temperature? - Definition & Measurement

In the most intuitive terms, temperature refers to how hot or cold something is. Learn more about temperature as a measure of the average kinetic energy of the particles in an object and test your knowledge with quiz questions.

Matter, Mass & Volume

3. Matter, Mass & Volume

After completing this lesson, you will be able to explain the difference between matter, mass and volume. You'll also be able to describe how two objects can have the same mass, but different volumes. A short quiz will follow.

Dalton's Law of Partial Pressures: Calculating Partial & Total Pressures

4. Dalton's Law of Partial Pressures: Calculating Partial & Total Pressures

In this lesson, you will learn how gases behave when they are mixed together and how to use Dalton's law of partial pressures to calculate partial and total pressures of gases. You will also learn how to use this information to explain how to find the partial pressure of a gas collected over water.

Boyle's Law: Gas Pressure and Volume Relationship

5. Boyle's Law: Gas Pressure and Volume Relationship

Have you ever wondered how an air powered water gun works? It uses the fantastic properties of gases to make a summer day more enjoyable! In this lesson, we will be discussing Boyle's Law and the relationship between pressure and volume of a gas.

Charles' Law: Gas Volume and Temperature Relationship

6. Charles' Law: Gas Volume and Temperature Relationship

In this lesson, we will discover why the wind blows and what causes a hot air balloon to rise, a couple of the applications of Charles' Law that explain the relationship between the volume and temperature of a gas.

Gay-Lussac's Law: Gas Pressure and Temperature Relationship

7. Gay-Lussac's Law: Gas Pressure and Temperature Relationship

You may know that you aren't supposed to put an aerosol can in a fire because it could explode, but do you know why? In this lesson, we will explain Gay-Lussac's law, which shows the relationship between the temperature and pressure of a gas.

The Ideal Gas Law and the Gas Constant

8. 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.

Colligative Properties and Raoult's Law

9. Colligative Properties and Raoult's Law

Learn how vapor pressure and osmotic pressure are colligative properties. Learn Raoult's Law and how to use it to determine the vapor pressure of a solution. Learn the equation for determining osmotic pressure and how to use it to determine the molar mass of a substance.

Using Colligative Properties to Determine Molar Mass

10. Using Colligative Properties to Determine Molar Mass

In this lesson, we will explore the effect of colligative properties on a solution. We will learn how to calculate freezing point depression and see how it can be used to calculate the molar mass of an unknown substance.

Phase Changes and Heating Curves

11. 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.

How to Calculate Specific Heat Capacity for Different Substances

12. How to Calculate Specific Heat Capacity for Different Substances

This lesson describes specific heat capacity and explains how the specific heat capacity of water helps to maintain a relatively constant temperature in nature. Learn how to identify the specific heat capacity of other common materials and how to calculate specific heat capacity with an experiment.

Heat of Fusion & Heat of Vaporization: Definitions & Equations

13. Heat of Fusion & Heat of Vaporization: Definitions & Equations

When a substance changes states, like from a solid to a liquid, a lot is happening. This lesson will examine the heat of fusion and the heat of vaporization. It will also explain both formulas.
