The Laws of Thermodynamics

1. 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.

The Zeroth Law of Thermodynamics

2. The Zeroth Law of Thermodynamics

After watching this video, you will be able to state the zeroth law of thermodynamics, what it means, and why it is important. A short quiz will follow.

State Functions in Thermochemistry

3. State Functions in Thermochemistry

This lesson defines state functions and explains why state functions are so useful in thermochemistry and thermodynamics. You'll also see a few examples of common state functions.

Enthalpy: Energy Transfer in Physical and Chemical Processes

4. 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.

Bond Energy: Definition & Equation

5. Bond Energy: Definition & Equation

Chemical reactions involve the breaking and forming of chemical bonds. In this video lesson, we will learn about bond energy and how we can use it to measure the overall energy change of a chemical reaction.

Using Hess's Law to Calculate the Change in Enthalpy of a Reaction

6. Using Hess's Law to Calculate the Change in Enthalpy of a Reaction

Want to make sure you don't blow yourself up during a chemical reaction? This lesson will help you avoid this by teaching you Hess's Law. This is one way to calculate the heat transferred, or enthalpy change, of a chemical reaction.

Predicting the Entropy of Physical and Chemical Changes

7. Predicting the Entropy of Physical and Chemical Changes

Ever wonder why your bedroom always ends up a mess within hours of you tidying up? That is the magic of entropy. In this lesson, you'll learn why disorder is the natural state of matter and how we can predict entropy change in a physical or chemical reaction.

Free Energy: Predicting the Spontaneity of a Reaction

8. Free Energy: Predicting the Spontaneity of a Reaction

Ever heard the phrase 'pushing Jell-O uphill on a hot day'? This describes a hopeless task. In this lesson, we will predict hopeful and hopeless reactions. Or put scientifically, predicting spontaneous (hopeful) and non-spontaneous (hopeless) reactions.

Standard Enthalpy of Formation: Explanation & Calculations

9. Standard Enthalpy of Formation: Explanation & Calculations

In this video lesson, we learn about the standard enthalpies of formation of substances. We will also learn how we can use these values as one way to calculate the standard enthalpy change of a chemical reaction.

Calorimetry: Measuring Heat Transfer and Heat Capacity

10. 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.

The Relationship Between Enthalpy (H), Free Energy (G) and Entropy (S)

11. The Relationship Between Enthalpy (H), Free Energy (G) and Entropy (S)

In this video lesson, we'll study free energy (G) and its relationship to enthalpy, entropy and temperature. You'll also learn why free energy (G) is the single most useful criterion for predicting the spontaneity and direction of a chemical reaction.

Endothermic and Exothermic Reactions

12. Endothermic and Exothermic Reactions

Explore a chemical reaction at the molecular level. Learn about exothermic and endothermic reactions, what they look like and what happens when they occur. Understand enthalpy and how you can use it to predict whether a reaction will be exothermic or endothermic.
