About This Chapter
Who's it for?
Anyone who needs help learning or mastering college-level general chemistry material will benefit from taking this course. There is no faster or easier way to learn college-level general chemistry. Among those who would benefit are:
- Students who have fallen behind in understanding phase diagrams or working with heating curves
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning science (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about liquids and solids
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How it works:
- Find videos in our course that cover what you need to learn or review.
- Press play and watch the video lesson.
- Refer to the video transcripts to reinforce your learning.
- Test your understanding of each lesson with short quizzes.
- Verify you're ready by completing the Liquids and Solids chapter exam.
Why it works:
- Study Efficiently: Skip what you know; review what you don't.
- Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
- Be Ready on Test Day: Use the Liquids and Solids chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any solids and liquids question. They're here to help!
- Study With Flexibility: Watch videos on any web-ready device.
Students will review:
This chapter helps students review the concepts in a Liquids and Solids unit of a standard college-level general chemistry course. Topics covered include:
- The properties of solids and liquids
- Critical point, triple point and phase equilibrium boundaries
- Phase changes and heating curves
- Crystal structures and the unit cell
1. The Kinetic Molecular Theory: Properties of Solids and Liquids
This lesson explores the kinetic molecular theory and how it pertains to the properties of solids and liquids. You'll learn the properties of solids and liquids, discover the types of intermolecular attractions that occur between them and gain an understanding how phase changes happen.
2. Phase Diagrams: Critical Point, Triple Point and Phase Equilibrium Boundaries
Learn what a phase diagram is and how to interpret phase diagrams. Discover how to use a phase diagram to locate the phase equilibrium boundaries. Also, learn what a triple point and critical point are and how to locate them on a phase diagram.
3. 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.
4. Crystal Structures and the Unit Cell
This crystallography lesson explores the structure and properties of crystals. You'll learn about the parts of a crystal structure, types of crystals and patterns created by unit cells.
5. What are Heating and Cooling Curves?
In this lesson, we will define heating and cooling curves. We will discuss how to understand and interpret such curves from both the heating and cooling perspectives by studying a generic example.
6. What is Aerogel? - Structure, Composition & Facts
There are lots of neat materials out there from rubber to cement to glass. But aerogel might top them all. This lesson will explore the structure and composition of this fascinating substance.
7. Aerogel: Uses & Mechanical Properties
Aerogel is a mysterious and fascinating material with numerous uses. This lesson will explore some of those uses as well as the challenges scientists face while working with aerogel's unique mechanical properties.
