Zeroth law: you CANNOT ignore the temperature of your heat engine. It states that ”when two bodies are in equilibrium with a third body, then they are also in thermal equilibrium with each other. This law allows the definition of a temperature range, such as temperature scales Celsius, Fahrenheit, Kelvin, Réaumur, Rankine, Newton and Leiden. Then the zeroth law of thermodynamics requires p’p” to be an equilibrium state for the composite system S’ + S”, so that, with a minor modification of the usual formulation, pp’p” is an equilib- rium state for S + S’ + S” (i.e., is stable under small perturbations of H + H’ + H”); this modified formulation is as physically cogent as the usual one. B. The zeroth law of thermodynamics states that "if two bodies A and B are separately in thermal equilibrium with a third body C, then A and B are in thermal equilibrium with each other..
