Study Notes
The Four Laws of Thermodynamics
-
0th Law of Thermodynamics: Establishes criteria for thermal equilibrium; if two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.
-
1st Law of Thermodynamics: Known as the Law of Conservation of Energy; energy cannot be created or destroyed, only transformed from one form to another.
-
2nd Law of Thermodynamics: States that the entropy of a closed system always increases over time; thermal energy will eventually equalize in isolated systems, leading to equilibrium.
-
3rd Law of Thermodynamics: Asserts that no system can achieve absolute zero temperature, where all atomic motion ceases.
Key Concepts
-
Entropy: Quantifies the amount of energy in a system that is not available to do work, serving as a measure of disorder.
-
Work: Defined as the energy transfer when an object is moved by an external force over a distance in the direction of that force.
-
Heat: Represents the energy transferred between systems due to temperature differences.
-
Energy: The capacity to perform work or induce change, fundamental to all processes in thermodynamics.
-
Absolute Zero: Represents the theoretical lowest temperature, at which atomic motion stops completely.
-
Thermal Equilibrium: Occurs when two or more objects in contact exchange thermal energy until they reach the same temperature, indicating no net energy transfer.
