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

The laws of thermodynamics deal with the relationship between heat and energy. Explore how the laws of thermodynamics function in everyday life, review the first and second laws, and learn about energy in a closed system.

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

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

Matter exists in four states: solid, liquid, gas, and plasma. There are six changes of phase that occur among these states. Learn more about the different kinds of phase change, their examples, and the energies involved in these changes.

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

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

Discover what a phase diagram is and how it graphs a substance's states of matter using temperature and pressure. Learn how to define and locate phase equilibrium lines, triple points, critical points, and supercritical fluids on phase diagrams.

What are Heating and Cooling Curves?

5. What are Heating and Cooling Curves?

Heating and cooling curves are graphs of temperature over time for different substances, demonstrating the phase changes. See the curves for heating and cooling to identify the phase changes from solid to gas (heating), and gas back to solid (cooling).

Mechanisms of Heat Transfer: Conduction, Convection & Radiation

6. Mechanisms of Heat Transfer: Conduction, Convection & Radiation

The three mechanisms that transfer heat include conduction, which is why a coffee mug gets hot when filled; convection, which is when heat is transferred via liquids; and, radiation, which is when heat is transferred by electromagnetic waves. Learn more about the mechanisms of heat transfer and the mobility of heat.

Calorimetry: Measuring Heat Transfer and Heat Capacity

7. Calorimetry: Measuring Heat Transfer and Heat Capacity

When a substance absorbs or gives out heat, the measurement of the heat transfer is calorimetry. Explore the meaning of calorimetry, the units of heat, specific heat capacity, and calorimetry and heat calculations.
