1. The Boltzmann Distribution: Temperature and Kinetic Energy of Gases
Gas particles are always moving around at random speeds and in random directions. This makes it difficult to determine what any one particle is doing at a given time. Luckily, the Maxwell-Boltzmann distribution provides some help with this.
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. Thermal Expansion: Definition, Equation & Examples
In this lesson, you will learn what thermal expansion is and discover an equation for calculating how much different materials expand. You'll look at a number of examples of thermal expansion. A short quiz will follow.
4. What is Heat Energy? - Facts & Calculation
In this lesson, you will learn about heat and that heat is a form of energy. You will learn about the properties of heat and the equations that will help you calculate heat in a variety of situations.
5. What is Thermal Energy? - Definition & Examples
This lesson defines and identifies examples of thermal energy everywhere from your kitchen to the Earth's core. We'll discuss geothermal energy, a renewable energy source, as well.
6. 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.
7. 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.
8. The Kinetic Theory of Matter: Definition & The Four States of Matter
Everything on Earth is made of matter, but that matter isn't always the same. Matter can exist in four different phases, and the kinetic theory of matter helps us understand the differences between those phases.
9. Types of Heating & Cooling Systems
You can choose from a number of different heating and cooling systems to make your home comfortable to live in. Watch this video to learn about the advantages and disadvantages of forced air, radiant heat, baseboard heat and geothermal systems.
10. Solar Energy: Understanding Active and Passive Solar Heating
Solar energy is the energy we harness from the sun. We can use this energy to heat our homes. Learn about the design elements needed for passive solar heating and the equipment needed for active solar heating.
