👉 In thermodynamics, a geometrically isothermal region is an idealization of a system where all energy and heat transfer occurs in a straight line. This concept is crucial for understanding how heat flows through solids and liquids at different temperatures. In this context, the term "geoisotherm" refers to a state in which all heat flow from a higher temperature source into a lower temperature sink, meaning that the total amount of heat transferred does not depend on the specific path taken by the energy or heat
