1. Kinetic Energy to Potential Energy: Relationship in Different Energy Types
This video defines and describes kinetic and potential energy. You'll learn how different types of energy can be classified as potential and kinetic. You'll also find out how kinetic and potential energy are transformed.
2. Energy Transformation: Definition, Types & Examples
In this lesson, you will learn about the different kinds of energy and how these types of energy can be transformed from one form to another. You will also learn about some uses of these energy transformations in everyday life.
3. Internal Energy of a System: Definition & Measurement
We often talk about individual types of energy, but how do you measure total energy? One way is to find the internal energy of a system. Let's learn what it means and how it is measured.
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. Heat of Fusion & Heat of Vaporization: Definitions & Equations
When a substance changes states, like from a solid to a liquid, a lot is happening. This lesson will examine the heat of fusion and the heat of vaporization. It will also explain both formulas.
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. 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.
8. What are Heating and Cooling Curves?
In this lesson, we will define heating and cooling curves. We will discuss how to understand and interpret such curves from both the heating and cooling perspectives by studying a generic example.
9. Bond Enthalpy: Definition, Calculations & Values
When a chemical reaction occurs, chemical bonds are broken and formed. Energy is required to break bonds when a chemical reaction occurs, and this is called the bond enthalpy. In this lesson, we will discuss the bond enthalpy in chemical reactions.
10. Energy Transformation: Photosynthesis vs. Cellular Respiration
In this lesson, explore how energy is converted between different forms during two biological processes: photosynthesis and cellular respiration. Learn how energy from the sun is harvested by plants and ultimately gives us the energy we need.
