Darwinism designates a distinctive form of evolutionary explanation for the history and diversity of life on earth. Its original formulation is provided in the first edition of On the Origin of Species in 1859.
The enthalpy - or internal energy - of a substance is a function of its temperature and pressure. The change in internal energy with respect to change in temperature at fixed pressure is the Specific Heat at constant pressure - cp.
The enthalpy (heat) for an exothermic reaction must be negative because more energy is released when the products are formed than is used when the reactants are broken up. Dexielene Villanueva Â· 1 year ago.
