Thermal Equilibrium and the Zeroth Law
Learning Objectives
- Students will be able to define thermal equilibrium and the Zeroth Law of Thermodynamics
- Students will be able to predict thermal equilibrium states in isolated systems
- Students will be able to explain the connection between temperature and thermal equilibrium
Core Concepts
- thermal_equilibrium
- zeroth_law
- temperature_equality
- isolated_system
- heat_flow
Formulas
$$T_A = T_B = T_C$$
At thermal equilibrium, all objects have the same temperature
Interesting Fact
The Zeroth Law is called 'zeroth' because it was recognized as fundamental after the First, Second, and Third Laws were already established
Key Scientist
Ralph H. Fowler
Named and formalized the Zeroth Law of Thermodynamics
Philosophy
The Zeroth Law of thermodynamics states that if two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. This allows the concept of temperature to be defined, providing a basis for comparing the thermal states of different systems.
