单词 thermochemistry
释义

thermochemistryn.

Etymology: < thermo- comb. form + chemistry n.Previous versions of the OED give the stress as: thermoˈchemistry.
That branch of chemical science which deals with the quantities of heat evolved or absorbed when substances undergo chemical change or enter into solution; e.g. the amount of heat evolved when hydrogen burns in oxygen or when sodium hydroxide is neutralized by sulphuric acid. Also sometimes used in a wider sense to include all relations of heat to substances, such as conductivity, specific heat, etc.
