Course Description

Over time, four basic rules about the effect of heat and pressure have been developed and documented. The oddly named “Zeroth Law” is usually listed first, but it was developed and documented after the first, second and third laws were already published. This course is designed to help you understand the laws of thermodynamics.

The first two laws of thermodynamics were developed together around the 1850s. The third law didn’t come along until 1912. Scientists realized the Zeroth Law was fundamental to the other laws, but it was impractical to renumber laws that the community had already become familiar with. This course details the Zeroth Law—Thermodynamic Equilibrium, the First Law of Thermodynamics—Conservation of Energy, The Second Law of Thermodynamics—Heat Transfer and Energy, and the Third Law of Thermodynamics—Entropy and Absolute Zero.

What You'll Learn

  • Explain why the Zeroth Law is fundamental to thermodynamics
  • Discuss the conservation of energy under the First Law of Thermodynamics
  • Define entropy and its connection to the laws of thermodynamics
  • Analyze the theoretical concept of absolute zero
  • Describe heat transfer and energy as covered by the Second Law of Thermodynamics
  • Identify the four laws of thermodynamics, including thermodynamic equilibrium

Key Takeaways

  • The four laws of thermodynamics describe the effect of heat and pressure and were developed and documented over time.
  • Although the Zeroth Law is usually listed first, it was developed and documented after the first, second, and third laws had already been published.
  • The first two laws of thermodynamics were developed together around the 1850s, while the third law came along in 1912.
  • Scientists recognized the Zeroth Law as fundamental to the other laws, but it was impractical to renumber laws the community had already become familiar with.
  • The course covers thermodynamic equilibrium (Zeroth Law), conservation of energy (First Law), heat transfer and energy (Second Law), and entropy and absolute zero (Third Law).
