State Functions in Thermochemistry

1. 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

2. 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.

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

3. 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.

Calorimetry: Measuring Heat Transfer and Heat Capacity

4. 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.

Predicting the Entropy of Physical and Chemical Changes

5. 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

6. 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.

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

7. 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.

Electrochemistry: Free Energy and Cell Potential Energy

8. Electrochemistry: Free Energy and Cell Potential Energy

Our modern lives are totally dependent on electricity. In this lesson, we learn about electricity spontaneously produced by electrochemical cells or batteries. We make the link between the potential energy they produce and Gibbs free energy.

Enthalpy Change: Definition & Calculation

9. Enthalpy Change: Definition & Calculation

In this lesson, we will learn how much energy is in a reaction and what can drive that reaction forward. We will also learn how to calculate the efficiency of that reaction.
