About This Chapter
Heat & Thermodynamics - Chapter Summary
Study these short and informative physics lessons to review concepts related to heat and thermodynamics. Our expert instructors will help you break down thermodynamic laws and gas properties, as well as the Carnot cycle and thermal equilibrium. You'll also evaluate the differences between radiation, convection and conduction. After completing the chapter, you should be able to:
- Recognize the characteristics/properties of different types of gas
- Define the concepts of thermal equilibrium and thermal conductivity
- Calculate a substance's specific heat capacity
- Differentiate between conduction, convection and radiation
- Explain the laws of thermodynamics and Newton's law of cooling
- Understand how the Carnot cycle works
These engaging video and text-based lessons are designed to be simple, straightforward and memorable so you can quickly review and retain the most important lesson topics. You can also submit questions to our instructors and print lesson transcripts to supplement your studying experience. These lessons are available whenever you have free time and you can access them on any device that has an Internet connection.
1. The Kinetic Molecular Theory: Properties of Gases
What makes a gas ideal? What types of characteristics do ideal gases have? In this lesson, we will discuss the many characteristics of gases and how knowing the microscopic properties of gas particles will help you understand the macroscopic properties of a gas.
2. Thermal Equilibrium: Definition, Formula & Example
In this lesson, you will learn what thermal equilibrium is, discover an equation that relates to thermal equilibrium, and go over an example of its use. A short quiz will follow.
3. How to Calculate Specific Heat Capacity for Different Substances
This lesson describes specific heat capacity and explains how the specific heat capacity of water helps to maintain a relatively constant temperature in nature. Learn how to identify the specific heat capacity of other common materials and how to calculate specific heat capacity with an experiment.
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. What is Thermal Conductivity? - Definition & Equation
Thermal conductivity is everywhere - from the laptop you use to the noodles you may have just cooked. In this lesson, you will explore the phenomenon and the formula that defines this physical property.
6. Newton's Law of Cooling
This lesson will introduce the reader to Newton's Law of Cooling, what it is, how it is experimentally verified, and how we can use it to calculate the cooling rate of objects in real-world examples.
7. The Laws of Thermodynamics
Learn about the first and second laws of thermodynamics. Find out how energy is generated, how it converts from one form to another, and what happens to energy in a closed system.
8. Efficiency & the Carnot Cycle: Equations & Examples
After watching this video, you will be able to explain the Carnot Cycle, including what it represents and how it works, and calculate the efficiency of a particular Carnot engine. A short quiz will follow.
