What are the laws of thermodynamics? Explain these laws with examples. What are the applications of these laws?

I think fire is a gas in state because we can’t say that fire is a liquid or a solid. I think if add some color to gas it may looks like fire.
 

=>Zeroth law of thermodynamics: If two systems are in thermal equilibrium independently 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 interacting 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. [2] With the exception of non-crystalline solids (glasses) the entropy of a system at absolute zero is typically close to zero, and is equal to the logarithm of the multiplicity of the quantum ground states
