Common Misconceptions

Conclusion

Enthalpy is a measure of the total energy of a thermodynamic system, encompassing internal energy (U) and the energy associated with the pressure and volume of a system. The enthalpy change (ΔH) arises when a system undergoes a process, such as expansion or compression. For instance, when a gas expands, its internal energy increases, resulting in a positive ΔH.
