For example, when the economy is healthy, you will typically see low unemployment and wage increases as businesses demand labor to meet the growing economy. A significant change in GDP, whether up or down, usually has a significant effect on the stock market.
Clearly, the molecular disorder in a gas will be greater than that in a liquid, so there must be an entropy increase upon vapourisation. Likewise, when a liquid freezes the mobile molecules of the liquid phase are forced to assume fixed positions in the solid phase. This will normally reduce the molecular disorder of the system, so there will usually be an entropy decrease that accompanies freezing.
what entropy measures is how much energy is spread out in a process t or how spread out the initial energy of a system becomes in that system at constant temperature
