The laws of thermodynamics describe the transport of heat and work in thermodynamic processes. These laws have become some of the most important in all of physics and other types of science associated with thermodynamics.[citation needed]
Classical thermodynamics, which is focused on systems in thermodynamic equilibrium, can be considered separately from non-equilibrium thermodynamics. This article focuses on classical or thermodynamic equilibrium thermodynamics.
The four principles (referred to as "laws")
The zeroth law of thermodynamics, which underlies the basic definition of temperature.
The first law of thermodynamics, which mandates conservation of energy, and states in particular that the flow of heat is a form of energy transfer.
The second law of thermodynamics, which states that the entropy of an isolated macroscopic system never decreases, or (equivalently) that perpetual motion machines are impossible.
The third law of thermodynamics, which concerns the entropy of a perfect crystal at absolute zero temperature, and which implies that it is impossible to cool a system all the way to exactly absolute zero.
