How Do You Spell ATHERMAL?

1. Athermal is an adjective that refers to a characteristic or property of a substance or system that does not undergo any change in temperature, regardless of the conditions of its surroundings or the input of thermal energy. The term "athermal" is derived from the combination of the prefix "a-" which denotes the absence or the opposite of something, and the root word "thermal" which relates to heat or temperature.

   In the context of thermodynamics, athermal substances or systems are those that do not experience any alteration in their temperature when subjected to heating or cooling processes. This phenomenon can arise due to various factors, such as the absence of molecular interactions or lack of heat capacity, which result in athermal behavior.

   For example, certain materials like superconductors exhibit athermal properties as they can conduct electric currents without experiencing a rise in temperature. Additionally, some chemical reactions may be classified as athermal if they occur without any accompanying heat changes.

   In scientific and technical applications, the concept of athermality is often crucial when designing devices, instruments, or systems that require precise temperature control or stability. By utilizing athermal materials or configurations, scientists and engineers can enhance accuracy and reliability in various fields such as metrology, optics, and electronics.

   In summary, athermal refers to the condition in which no alteration in temperature occurs regardless of external thermal influences, providing stability and maintaining a constant temperature within a substance or system.

2. Not thermal, noting mineral springs the water of which issues from the ground at a temperature below 60° F.
