 # Explain Laws of Thermodynamics

“When a given object or body A is in thermal equilibrium with a body or object B, as we will as separately with a body or object C also, then it’s necessary that B as we will as C would also be in thermal equilibrium with each other “. . This statement tells us that thermal equilibrium is simply a Euclidean relation between. thermodynamic systems. Thermal equilibrium is also a proven reflexive relation. Equivalence relations are those which are both reflexive as we will as Euclidean. Hence thermal equilibrium is simply a transitive relationship. Another result is that the equilibrium relationship is always symmetric: If the body A is in thermal equilibrium with another body or object B, then B is in thermal equilibrium with A. Hence it can be said that two systems are in thermal equilibrium with each other. Thermodynamics is simply a macroscopic science which studies various energy inter-actions, notably heat as we will as work transfer, with matter, that brings about significant changes in the macroscopic properties of a substance that are measurable. It’s basically a phenomenological science based on certain laws of nature which are always obeyed as we will as never seem to be violated. These are the basic laws of thermodynamics Zeroth law of thermodynamicsFirst law of thermodynamicsSecond law of thermodynamicsThird law of thermodynamics.
