Interpretation of temperature in liquids/solids

[QUOTE="Lord Jestocost, post: 6867265, member: 638573"] Regarding the "physical interpretation of temperature", I would rely on “An Introduction to Thermal Physics” by Daniel V. Schroeder (Oxford University Press 2021). Schroeder's proposal for a theoretical definition of temperature is: “[B][I]Temperature[/I][/B][I] is a measure of the tendency of an Object to spontaneously give up energy to its surroundings. When two objects are in thermal contact, the one that tends to spontaneously lose energy is at the higher temperature.[/I]” On base of this theoretical definition, one arrives at the thermodynamic definition of temperature: "[I]The [B]temperature[/B] of a system is the reciprocal of the slope of its entropy vs. energy graph. The partial derivative is to be taken with the system's volume and number of particles held fixed;* more explicitly,[/I] $$\frac 1 T\equiv\left( \frac {\partial S} {\partial U}\right)_{N,V} .$$" [/QUOTE]
