About This Chapter
Heat & Temperature in Physics - Chapter Summary
In this chapter, you will be introduced to temperature, heat and thermal expansion. The formula and definition of latent heat will be introduced along with calorimetry, which measures heat transfer. A study of the greenhouse effect and enthalpy is also included.
The lessons continue with the laws of thermodynamics, renewable energy sources and a description of heat of fusion. Once you have completed this chapter, you should be able to:
- Differentiate between heat and temperature
- Describe thermal expansion and heat transfer
- Define calorimetry
- Explain the impact of the greenhouse effect
- Detail the laws of thermodynamics
- Give examples of latent heat and renewable energy sources
- Calculate specific heat capacity
- Use the equation for heat of fusion
In generally ten minutes or less, our short videos engage students and outline important study topics. Take the lesson quizzes to make sure you understand the material. If you'd like to watch just one portion of a video lesson, use the video tabs feature in the Timeline to jump directly to the information you'd like to view. You can review these study materials at any time on any computer, mobile phone or tablet.
1. What is Temperature? - Definition & Measurement
In the most intuitive terms, temperature refers to how hot or cold something is. Learn more about temperature as a measure of the average kinetic energy of the particles in an object and test your knowledge with quiz questions.
2. What is Heat? - Definition & Explanation
In this lesson, you will learn the definition of heat and find out how it differs from temperature. You will also explore practical applications of heat such as expansion, thermodynamics, heat transfer, specific heat, phase transitions, and heat engines.
3. Thermal Expansion & Heat Transfer
After watching this video, you will be able to explain how heat transfers by conduction through a slab of material, explain how the shape and size of an object varies as it expands, and solve problems involving conduction. A short quiz will follow.
4. Latent Heat: Definition, Formula & Examples
Heat is an important component of phase changes. This lesson will delve into the concept of latent heat and how it affects of the behavior of matter during phase changes.
5. 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.
6. What is the Greenhouse Effect? - Definition & Impact
After completing this lesson, you will be able to explain what the greenhouse effect is, how it works, how significant it is on Earth, and how humans have affected it. A short quiz will follow.
7. Enthalpy: Energy Transfer in Physical and Chemical Processes
This video explores the relationship between chemistry and energy. We learn the general properties of energy and the concepts of temperature and heat. We will learn about energy flow and consider the enthalpy change during chemical reactions.
8. 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.
9. What Is a Renewable Energy Source? - Definition & Example
Right now, you are using electricity to power your computer. Most of our power comes from nonrenewable sources that can run out. In this lesson, learn about the many types of renewable energy sources that will never run out and could be used instead.
10. 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.
11. Heat of Fusion: Definition, Equation & Examples
This lesson will examine the heat of fusion, which is the energy required for matter to change between a liquid and a solid. In this lesson, we review the concepts of latent heat and work through a problem using our new understanding of the heat of fusion.
