Temperature measures a system's energy distribution from "summary" of Thermodynamics and an Introduction to Thermostatistics by Herbert B. Callen
The concept that temperature measures a system's energy distribution is fundamental to understanding the behavior of physical systems. In thermodynamics, temperature is not simply a measure of how hot or cold something is, but rather a reflection of the distribution of energy within the system. When we say that a system has a certain temperature, what we are really saying is that the energy of the system is distributed in a particular way among its constituent particles. At a higher temperature, the energy is more evenly distributed among the particles, while at a lower temperature, the energy is more concentrated in certain particles. This concept is closely related to the idea of entropy, which is a measure of the disorder or randomness of a system. In a system with a higher temperature, the particles are moving more rapidly and are more likely to be in a state of disorder. This leads to a higher entropy for the system. Temperature also plays a crucial role in determining the direction of heat flow between two systems. Heat will naturally flow from a system at a higher temperature to a system at a lower temperature in order to equalize the energy distribution between the two systems. In summary, temperature is not just a measure of hotness or coldness, but rather a reflection of how energy is distributed within a system. It is intimately linked to concepts such as entropy and heat flow, and plays a central role in understanding the behavior of physical systems.
