Entropy of fusion — The entropy of fusion is the increase in entropy when melting a substance. This is always positive since the degree of disorder increases in the transition from an organized crystalline solid to the disorganized structure of a liquid. It is… … Wikipedia
Enthalpy of vaporization — The enthalpy of vaporization, (symbol Delta{} {v}H), also known as the heat of vaporization or heat of evaporation, is the energy required to transform a given quantity of a substance into a gas. It is measured at the normal boiling point of the… … Wikipedia
Introduction to entropy — Thermodynamic entropy provides a measure of certain aspects of energy in relation to absolute temperature. The thermodynamic entropy S, often simply called the entropy in the context of thermodynamics, is a measure of the amount of energy in a… … Wikipedia
Standard molar entropy — In chemistry, the standard molar entropy is the entropy content of one mole of substance, under standard conditions (not standard temperature and pressure STP).The standard molar entropy is usually given the symbol S o, and the units joules per… … Wikipedia
Trouton's rule — Trouton’s rule states that the entropy of vaporization is almost the same value, about 87 88 J K 1 mol 1, for various kinds of liquids. The entropy of vaporization is defined as the ratio between the enthalpy of vaporization and the boiling… … Wikipedia
