Definition: The term "isogeothermic" in physics refers to a material that has a temperature distribution that can be described by an isothermal process but with a temperature gradient. This means that the temperature of an object increases or decreases at different rates depending on its distance from a fixed reference point, such as a thermometer or a heat source. Isogeothermic materials are typically used in applications where temperature change is important and the material can be accurately modeled by a mathematical model that takes into account temperature gradients
