Temperature is the quantity that most clearly marks thermodynamics because it is the defining state property that governs heat transfer and thermal equilibrium. The zeroth law establishes that temperature is the measurable criterion for when systems are in the same thermal state, enabling a universal scale to compare different bodies. This makes it the key link between energy and heat flow, allowing thermodynamics to describe how energy is transformed and redistributed when objects interact, and to formulate the fundamental relations that connect heat, work, and state variables like pressure and volume. While heat, energy, and even entropy are important concepts, temperature uniquely provides a universal, measurable driver of thermal processes and equilibrium, which sets thermodynamics apart from other sciences.
