Standard enthalpy 02

WebbEntropy is a measure of disorder. Statistical thermodynamics defines the entropy of a system in the following way: S = k l n ( W) S = k\ ln (W) S = k ln(W) where: k - Boltzman's constant, W - the number of ways in which the macroscopic thermodynamic state of the system can be realized through microscopic states.

WebbThe standard enthalpy of fusion is the enthalpy change when one mole of a substance transforms from a solid state to a liquid state under standard conditions. The melting of ice is one of the most familiar examples of a system transitioning from a solid to a liquid. WebbThe standard enthalpy of formation for a wide range of substances was already determined. It is the change of enthalpy which occurs when 1 mole of a substance forms from constituent elements while all the other substances remain in standard states.

WebbThe standard enthalpy of formation of a substance is the enthalpy change that occurs when 1 mole of the substance is formed from its constituent elements in their standard states. A pure element in its standard state has a standard enthalpy of formation of zero.

WebbThe enthalpy of vaporization(symbol ∆Hvap), also known as the (latent) heat of vaporizationor heat of evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas. The enthalpy of vaporization is a function of the pressureat which that transformation takes place.
