The Zeroth Law of Thermodynamics states that if two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. This law forms the basis for the concept of temperature and helps establish a consistent way to measure it. By defining temperature through equilibrium, it connects to how properties of systems can indicate their state and whether they are in equilibrium with each other.
congrats on reading the definition of Zeroth Law of Thermodynamics. now let's actually learn it.
