Key terms entropy A thermodynamic property that is the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work. ferromagnetic the basic mechanism by which certain materials form permanent magnets, or are attracted to magnets microstate The specific detailed microscopic configuration of a system. paramagnetic attracted to the poles of a magnet quantized Expressed or existing only in terms of discrete quanta; limited by the restrictions of quantization. standard entropy Entropy of a substance at 1 atm pressure. surroundings All parts of the universe that are not within the thermodynamic system of interest. third law of thermodynamics a law which states that the entropy of a perfect crystal at absolute zero is exactly equal to zero Free to share, print, make copies and changes.

Entropy is a measure of the degree of spreading and sharing of thermal energy within a system. This "spreading and sharing" can be spreading of the thermal energy into a larger volume of space or its sharing amongst previously inaccessible microstates of the system.
