WebMass transfer by convection involves the transport of material between a boundary surface (such as solid or liquid surface) and a moving fluid or between two relatively immiscible, moving fluids. Convective mass … WebPurpose: Enthalpy (ΔH) is a measurement of the total amount of energy in a system. For chemical reactions, the enthalpy can change. During an endothermic reaction, energy is absorbed into the system and enthalpy increases. During an exothermic reaction energy is released by the system and the enthalpy decreases.
