WitrynaNaOH and H2O reaction to form Na+ and OH- ions in solution.It is EXOTHERMIC because more energy is RELEASED when then ions attach to water molecules than is ... The 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 notable constant parameter is the volumetric heat capacity (at least for solids) which is around the value of 3 megajoule per cubic meter per kelvin:
