Go to Standard state and Standard enthalpy of formation for listing of standard enthalpy of formation and standard entrypy for more than 370 inorganic substances.
Work, heat and energy systems.
The First Law of Thermodynamics simply states that energy can be neither created nor destroyed (conservation of energy). Thus power generation processes and energy sources actually involve conversion of energy from one form to another, rather than creation of energy from nothing.
Entropy and disorder.
Thermodynamic properties of saturated and superheated ammonia R-717 like specific volume, enthalpy and entropy.
Heat vs. work vs. energy.
Definition and explanation of the terms standard state and standard enthalpy of formation, with listing of values for standard enthalpy and Gibbs free energy of formation, as well as standard entropy and molar heat capacity, of 370 inorganic compounds.
Vapor and steam enthalpy, specific enthalpy of saturated liquid, saturated vapor and superheated vapor.
Basic steam thermodynamics - entropy diagram.
The entropy of steam superheated to temperatures above saturation points.
Internationally agreed, internally consistent, values for the thermodynamic properties (standard enthalpy of formation, entropy and [H°(298)-H°(0)]) of key chemical substances.
The entropy of a substance is zero if the absolute temperature is zero.
The most common units of heat BTU - British Thermal Unit, Calorie and Joule.
Thermal properties of water at different temperatures like density, freezing temperature, boiling temperature, latent heat of melting, latent heat of evaporation, critical temperature and more.
