Introduction to Chemistry & Matter - Chapter Summary
Study chemistry and matter concepts with help from this fun introduction. Science instructors have developed short lessons that closely examine the metric system, matter, chromatography, condensation and much more. Navigate the lessons at your own pace. In no time, you will be able to:
- List metric units and report measurements accurately
- Convert among units using conversion factors
- Use scientific notation to make calculations
- Identify and describe the uses of various pieces of lab equipment
- Explain differences between physical and chemical properties
- Differentiate between physical and chemical change and classify different phases of matter
- Discuss chromatography, distillation and filtration and choose the method for separating a given mixture
Lessons are accessible as videos that average about 8 minutes or full transcripts that you can read and print. Navigate the lessons in any order and as many times as needed to enhance your comprehension of chemistry and matter. Expand your knowledge by sending any lesson topic questions you have to our experts. Assess your understanding of this chapter with multiple-choice quizzes and a practice chapter exam.
1. The Metric System: Units and Conversion
Just like you and your friend communicate using the same language, scientists all over the world need to use the same language when reporting the measurements they make. This language is called the metric system. In this lesson we will cover the metric units for length, mass, volume, density and temperature, and also discuss how to convert among them.
2. Unit Conversion and Dimensional Analysis
How is solving a chemistry problem like playing dominoes? Watch this lesson to find out how you can use your domino skills to solve almost any chemistry problem.
3. Significant Figures and Scientific Notation
Are 7.5 grams and 7.50 grams the same? How do scientists represent very large and very small quantities? Find out the answers to these questions in this video.
4. Chemistry Lab Equipment: Supplies, Glassware & More
When you bake a cake, you use different tools for each step in the process: a bowl for mixing, cups for measuring ingredients and an oven for baking. In this lesson, you will discover the name and purpose of many of the different tools that are used in the chemistry lab.
5. 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.
6. States of Matter and Chemical Versus Physical Changes to Matter
The world around us is constantly changing. Chemists put those changes into two main categories: physical changes and chemical changes. This lesson will define and provide examples of each.
7. Chromatography, Distillation and Filtration: Methods of Separating Mixtures
What are some ways that mixtures can be separated? Watch this video to explore several examples of ways you can separate a mixture into its individual components.
8. What is Condensation? - Definition & Examples
Condensation is the process of a substance in a gaseous state transforming into a liquid state. This change is caused by a change in pressure and temperature of the substance. In this lesson, you will learn about some examples and test your knowledge with a short quiz.
