The four laws of thermodynamics are: Zeroth law of thermodynamics: If two systems are in thermal equilibrium respectively with a third system, they must be in thermal equilibrium with each other. This law helps define the notion of temperature. First law of thermodynamics: When energy passes, as work, as heat, or with matter, into or out from a system, its internal energy changes in accord with the law of conservation of energy. Equivalently, perpetual motion machines of the first kind are impossible. Second law of thermodynamics: In a natural thermodynamic process, the sum of the entropies of the participating thermodynamic systems increases. Equivalently, perpetual motion machines of the second kind are impossible. Third law of thermodynamics: The entropy of a system approaches a constant value as the temperature approaches absolute zero. With the exception of glasses the entropy of a system at absolute zero is typically close to zero, and is equal to the log of the multiplicity of the quantum ground state. read less

This law helps define the notion of temperature. 1st law : Energy can neither be created nor destroyed. 2nd law : Entropy of universe always increases 3rd law : The entropy of a perfect crystal, at absolute zero (zero kelvins), is exactly equal to zero. read less

1...The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in a chemical reaction. 2...The second law of thermodynamics states that the entropy of any isolated system not in thermal equilibrium almost always increases. 3...The third law of...

How can I learn physics without any tuition coaching or school in class 12?
Lots of material are available in youtYou on different topics. Some are good and some are average ore not good. In Physics, H C Verma is good book. In Physics self learning takes time but whatever you learn, it is lifelong.
