The following table of specific heat capacities gives the volumetric heat capacity, as well as the specific heat capacity of some substances and engineering materials, and (when applicable) the molar heat capacity.. Generally, the most constant parameter is notably the volumetric heat capacity (at least for solids), which is notably around the value of 3 megajoule per cubic meter and kelvin: The standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements, with all substances in their standard states.The standard pressure value p ⦵ = 10 5 Pa (= 100 kPa = 1 bar) is recommended by IUPAC, although prior to 1982 the value 1.00 atm (101.325 kPa) was used. The product is a complex ion that has a coordinate covalent bond between the iron cation and an atom (probably the S atom) from the thiocyanate anion. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.
