Entropy is the tendency of systems to move from a higher to a lower state of organization at the molecular level. It affects diffusion, phase change, and location. Entropy is a mathematical measure of a change from higher to lower potential energy, related to the second law of thermodynamics. It measures how much energy is […]
Standard entropy measures the amount of heat energy in a closed system that is unavailable for work and increases over time. It is expressed as S° in joules per mole of Kelvin temperature. The laws of thermodynamics state that energy cannot be created or destroyed, and statistical mechanics is used to calculate energy transfer. The […]
