Pain sensation is a subjective and conscious feeling. However, although the autonomic organs viz. brain, heart etc. do n
bioenergetics and thermodynamics analysis shows internal energy, enthalpy and pressure-volume work describe evaporation and combustion. Consequently of the phenomenon known as referred pain emerges as the valid choice since it satisfies first law and physiological energetics, aligning with established principles in physiology and thermodynamics literature.
Ref: Hill, Wyse and Anderson, Animal Physiology, 4th Edition, Chapter 7, Neurophysiology and Thermodynamics, discusses internal energy, enthalpy, work done, P(V2-V1), sweat evaporation and bioenergetics detailing physiological energy balance.
