MTEL Physics: Principles of Thermodynamics - Chapter Summary

Use our lessons and quizzes to review information about the principles of thermodynamics as you study for the MTEL Physics exam. You'll refresh your knowledge of topics related to heat and energy and be prepared for questions on the exam about:

  • Converting between Kelvin and Celsius
  • Diagrams showing changes in energy and heat
  • Phase changes and heating curves
  • Radiation and heat transfer
  • The Stefan-Boltzmann law
  • The second law of thermodynamics

Our expert instructors have designed these lessons and quizzes to equip you for success on test day. Armed with information about heat transfer, energy and entropy, you'll be prepared for questions on thermodynamics.

5 Lessons in Chapter 11: MTEL Physics: Principles of Thermodynamics
Temperature Units: Converting Between Kelvins and Celsius

1. Temperature Units: Converting Between Kelvins and Celsius

Have you ever wondered what the lowest possible temperature is? In this lesson, you will learn what temperature measures. You will also be introduced to the Kelvin scale (an absolute scale) and learn how it relates to the Celsius scale.

Changes in Heat and Energy Diagrams

2. Changes in Heat and Energy Diagrams

Did you know that temperature and heat are not the same thing? Did you know that the temperature of water doesn't change when it boils? This lesson describes the relationship between heat and temperature. Diagrams are used to illustrate the relationship between heat and temperature during phase changes.

Phase Changes and Heating Curves

3. Phase Changes and Heating Curves

Learn the phases - gas, liquid, solid and plasma. Learn what a phase diagram is and what terms describe the movement between phases: melting, sublimating, freezing, vaporization, condensation, and deposition. Discover why heating curves have plateaus, what a phase transition is, and what happens during this transition.

Radiation, Heat Transfer & the Stefan-Boltzmann Law

4. Radiation, Heat Transfer & the Stefan-Boltzmann Law

After watching this lesson, you will be able to explain how radiative heat transfer works, give some real-life examples of radiation, and use the Stefan-Boltzmann Law to complete radiation calculations. A short quiz will follow.

Second Law of Thermodynamics: Entropy and Systems

5. Second Law of Thermodynamics: Entropy and Systems

In this lesson, we'll learn about the second law of thermodynamics. By studying this law, you'll understand how energy works and why we're all moving towards eventual chaos and disorder.
