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. Measuring Temperature in the Lab: Instruments & Process
In this lesson, discover what temperature is a measurement of while learning how to properly measure temperature in a lab. Learn about the important instruments needed for this essential lab skill.
3. Degrees Fahrenheit: Definition & Conversion
In this lesson, we will define the degree and the Fahrenheit temperature scale. We will also compare the Fahrenheit scale to the other temperature scales and learn how to convert between them.
4. 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.
5. 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.
6. 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.
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. Entropy: Equation & Calculations
After watching this lesson, you will be able to apply the concept of entropy to real life situations and complete calculations of entropy for a closed system. A short quiz will follow.
