What are the Different Types of Energy?

1. What are the Different Types of Energy?

Energy is one of the most fundamental concepts in many scientific fields. Learn more about its different types, subsequently testing your knowledge with a quiz.

The Laws of Thermodynamics

2. 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.

Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition

3. Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition

Substances on Earth can exist in one of four phases, but mostly, they exist in one of three: solid, liquid or gas. Learn the six changes of phase: freezing, melting, condensation, vaporization, sublimation and deposition.

Phase Diagrams: Critical Point, Triple Point and Phase Equilibrium Boundaries

4. Phase Diagrams: Critical Point, Triple Point and Phase Equilibrium Boundaries

Learn what a phase diagram is and how to interpret phase diagrams. Discover how to use a phase diagram to locate the phase equilibrium boundaries. Also, learn what a triple point and critical point are and how to locate them on a phase diagram.

What are Heating and Cooling Curves?

5. 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.

Mechanisms of Heat Transfer: Conduction, Convection & Radiation

6. 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.

Calorimetry: Measuring Heat Transfer and Heat Capacity

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.
