What Are Enharmonic Equivalents? In a nutshell, the term enharmonic equivalent means notes that sound the same as one another but are named or âspelledâ differently (and this concept can also be extended to include intervals and scales). The musical alphabet consists of seven main notes represented by seven letters: A-B-C-D-E-F-G.
Enthalpy itself is a thermodynamic potential, so in order to measure the enthalpy of a system, we must refer to a defined reference point; therefore what we measure is the change in enthalpy, Î´ H.The Î´ H is a positive change in endothermic reactions, and negative in heat-releasing exothermic processes.For processes under constant pressure, Î´ H is equal to the change in the internal energy of the system, plus the pressure-volume work that the system has done on its surroundings.nthalpy itself is a thermodynamic potential, so in order to measure the enthalpy of a system, we must refer to a defined reference point; therefore what we measure is the change in enthalpy, Î´ H.
