Isenthalpic process

An isenthalpic process is a thermodynamic process in which the enthalpy of the system remains constant. In other words, during an isenthalpic process, there is no change in the total heat content, expressed as \( H = U + PV \), where \( H \) is the enthalpy, \( U \) is the internal energy, \( P \) is the pressure, and \( V \) is the volume of the system.
