About This Chapter
MTEL Chemistry: Thermodynamics - Chapter Summary
Utilize the lessons in this chapter to study the various laws of thermodynamics, and explore methods for understanding the relationship between energy and temperature to prepare for the MTEL Chemistry exam. By the end of this chapter you will have reviewed:
- The laws of thermodynamics
- Thermochemistry functions
- Enthalpy and calculating changes
- The equation for bond energy
- Free energy and predicting spontaneity
- The connection between enthalpy, free energy and entropy
- The differences between exothermic and endothermic reactions
Each lesson has been prepared by professionals to help you best retain the information by providing several effective methods for learning. There is a video included in each lesson along with its transcript and a clickable timeline in case you need to review a portion of the video. At the end of each lesson, there is a self-assessment quiz you can take to test your application of the knowledge.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
