About This Chapter
Thermal Physics - Chapter Summary and Learning Objectives
Use the lessons in this chapter to gain an understanding of the physical laws involving heat. You'll be guided through each video by experienced instructors who use real world examples to demonstrate each topic. The concepts covered include temperature scales, phase changes, heating curves and heat transfer. Other lessons look at how heat can cause expansion and why heat transfer occurs. The quizzes that accompany each video will allow you to assess your knowledge. By the conclusion of this chapter, you should be informed about the following:
- Fahrenheit and Celsius scales of measuring temperature
- What happens in a phase change
- Interpreting heating curves
- Thermal expansion
- Calculating heat capacity

1. Introduction to Thermal Physics
After watching this lesson you will be able to explain what thermal physics is, as well as the various areas of study and topics that make it up. A short quiz will follow.
2. Temperature Units: Converting Between Kelvins and Celsius
Have you ever wondered what the lowest possible temperature is? In this lesson, you will learn what temperature measures. You will also be introduced to the Kelvin scale (an absolute scale) and learn how it relates to the Celsius scale.
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. Mechanisms of Heat Transfer: Conduction, Convection & Radiation
There are three main ways that heat is transferred between substances or objects. In this video lesson you'll learn about each one, and identify the differences between them.
5. Heat Transfer & Phase Changes
After watching this lesson, you will be able to explain what heat transfer is and describe the various phase changes that can result from heat transfer in terms of the position of the molecules. You will also be able to give the names of those phase changes. A short quiz will follow.
6. Thermal Expansion: Importance & Examples
After watching this video, you will be able to explain what thermal expansion is, why it is important, provide some examples of thermal expansion in real life and complete basic thermal expansion calculations. A short quiz will follow.
7. Calorimetry: Measuring Heat Transfer and Heat Capacity
This video lesson explains the technique of calorimetry used to measure heat transfer in chemical reactions. You will see how different materials have different specific heat capacities. You will learn how to carry out heat calculations using a simple equation.
