Matter: Physical and Chemical Properties

1. Matter: Physical and Chemical Properties

Matter, or material substances, are identified based on their physical and chemical properties. Explore how this process works and learn how chemists use different properties to determine the classification of matter.

States of Matter: Solids, Liquids, Gases & Plasma

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

There are four states of matter: solid, liquid, gas, and plasma. Explore the characteristics of each state of matter and how they relate to and differ from each other.

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

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

The kinetic theory of matter states that all matter is comprised of minuscule particles in random motion, with space between each particle. Learn about the definition of the kinetic theory of matter, phase changes, and the four states of matter.

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

Electrolytes are ionic compounds that can complicate the boiling-point elevation equation. Discover how to calculate the boiling-point elevation of any solution through equations, examples, background, and review in this lesson.

Osmotic Pressure: Definition & Formula

6. Osmotic Pressure: Definition & Formula

Osmotic pressure is created by the movement of water across a membrane through the process of osmosis. Learn the definition of osmotic pressure and the formula used to calculate it, and practice using it by solving practice problems.

Vapor Pressure: Definition, Equation & Examples

7. Vapor Pressure: Definition, Equation & Examples

Vapor pressure builds when the number of water molecules lost through evaporation is the same as the number of water molecules that turn to liquid through condensation in a contained space. Learn about the Clausius-Clapeyron equation through an example of how temperature affects pressure and Raoult's law involving mixtures.

The Ideal Gas Law and the Gas Constant

8. The Ideal Gas Law and the Gas Constant

The ideal gas law can be used to predict real gas behavior. Learn about this law, including its equation, and understand how to use the equation to solve a gas problem. Explore the concepts used by the ideal gas law such as the gas constant.

Comparing Solutions, Suspensions & Colloids: Properties & Examples

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

A mixture of substances appears differently depending on if the substances actually mix, and are evenly distributed. Learn the properties of the three types of mixtures commonly observed through examples of solutions, suspensions, and colloids.
