laws of thermodynamics

Explain how these apply:

*Zeroth: You must play the game.

*First: You can't win.

*Second: You can only break even at absolute zero.

*Third: You can't reach absolute zero.

    * The zeroth law of thermodynamics allows the assignment of a unique temperature to systems which are in thermal equilibrium with each other.

    * The first law of thermodynamics mandates conservation of energy and states in particular that the flow of heat is a form of energy transfer.

    * The second law of thermodynamics states that the entropy of an isolated macroscopic system never decreases, or, equivalently, that perpetual motion machines are impossible.

    * The third law of thermodynamics concerns the entropy of a perfect crystal at absolute zero temperature, and implies that it is impossible to cool a system to exactly absolute zero.
