Matter: Physical and Chemical Properties

1. Matter: Physical and Chemical Properties

How are substances identified? There are two major ways we can describe a substance: physical properties and chemical properties. Learn about how chemists use properties to classify matter as either a mixture or a pure substance.

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

2. 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 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.

Freezing Point: Definition & Equation

4. Freezing Point: Definition & Equation

This lesson describes what is required on the molecular level for a substance to freeze. The equation for the amount of energy needed for this change to occur is presented along with an example.

Calculating Boiling-Point Elevation of a Solution

5. Calculating Boiling-Point Elevation of a Solution

In this lesson, you will learn how to calculate the boiling point of a solution using a simple equation. Additionally, you will review the concepts of solutions, molality, and electrolytes.

Osmotic Pressure: Definition & Formula

6. Osmotic Pressure: Definition & Formula

This lesson will define osmotic pressure, provide the formula for calculating osmotic pressure, and show you how to solve problems using the formula. After the lesson, there will be a brief quiz so you can test what you've learned.

Vapor Pressure: Definition, Equation & Examples

7. Vapor Pressure: Definition, Equation & Examples

This lesson explains the definition of vapor pressure, describes how vapor pressure changes as a function of temperature according to the Clausius-Clapeyron equation, and shows how to determine the vapor pressure of a single component in a mixture of liquids using Raoult's Law.

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.

Comparing Solutions, Suspensions & Colloids: Properties & Examples

9. Comparing Solutions, Suspensions & Colloids: Properties & Examples

With a few simple observations, you can classify a mixture as a solution, suspension or colloid. Learn how we use properties, such as visibility of particles, how light is affected and the ability of particles to settle out to classify mixtures.
