The zeroth law of thermodynamics was proposed or formulated a long time after the first three laws of thermodynamics . This new law defined the temperature in a way that was much clearer than what the other three laws stated. Zeroth law of thermodynamics – The zeroth law of thermodynamics is a generalized statement about bodies in contact at thermal equilibrium and is the basis for the concept of temperature. – The most common definition of the zeroth law of thermodynamics is: If two thermodynamic systems are in thermal equilibrium with a third, they are also in thermal equilibrium with each other. – The term zeroth law was coined by Ralph H. Fowler. – In many ways, the law is more fundamental than any of ... Learn what is zeroth law of thermodynamics , how it defines temperature and thermal equilibrium, and how it is used in thermometers and other devices. Find out the difference between zeroth law and other laws of thermodynamics , and test your knowledge with MCQs.
