What is the symbol used to represent enthalpy?

Enthalpy is a thermodynamic property that represents the total heat content of a system. It is commonly used in chemistry and physics to measure the amount of energy exchanged during a chemical reaction or a phase change at constant pressure. The symbol used to denote enthalpy is "H".

This representation is fundamental in various applications, such as calculating changes in enthalpy during reactions, which can be vital for understanding endothermic and exothermic processes. The other symbols mentioned correspond to different thermodynamic properties; for example, "S" typically represents entropy, "G" signifies Gibbs free energy, and "E" can represent internal energy. Each symbol plays a distinct role in thermodynamics and understanding physical science, with "H" being uniquely attributed to enthalpy.
