What is the term for heat released by the mixture of matter in a liquid?

The term for heat released by the mixture of matter in a liquid is known as "heat of solution." This refers to the thermal energy that is either absorbed or released when a solute dissolves in a solvent. When the solute is mixed into the solvent, interactions occur at the molecular level, resulting in changes in energy. If the process of dissolving releases heat, it is exothermic, while if it absorbs heat, it is endothermic. These thermal changes are important in various chemical and physical processes, such as when salts dissolve in water or when acetone is mixed with water.

The other terms listed refer to different concepts: electrical heat energy pertains to heat produced by electrical resistance, resistance heating refers to the generation of heat through electrical resistance in conductive materials, and dielectric heating involves the heating of non-conductive substances when placed in an alternating electric field. None of these relate specifically to the heat associated with the dissolution process in liquids.
