👉 In thermodynamics, a process is considered to be "hydrothermally" when it involves the transfer of heat from a system that has lower temperature into one with higher temperature. This can happen through various means such as conduction, convection, or radiation. For example, in a boiling water kettle, hot liquid water is transferred from the hotter surface (the pot) to the colder bottom (the water). The process is described as "hydrothermally" because it involves heat transfer
