 Laws of thermodynamics

The laws of thermodynamics are fundamental principles that describe how energy behaves in physical systems. There are four main laws, often numbered from zero to three: 1. **Zeroth Law of Thermodynamics**: This law establishes the concept of temperature. It states that if two systems are each in thermal equilibrium with a third system, they are in thermal equilibrium with each other. This law allows for the definition of temperature, making it a foundational principle in thermodynamics.
