They are all driven by thermodynamics. The four laws of thermodynamics tell us about energy behaviour, such as how and why heat, which is a form of energy, transfers between different objects. Let’s take a closer look.
Zeroth Law of Thermodynamics
Thermal equilibrium is a state in which all parts of a system are at the same temperature. The Zeroth Law of Thermodynamics states that if two thermodynamic systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each
