The Fluctuation-imposed Limit for Temperature Measurement
... is to be measured, is assumed to be isothermal and to have infinite heat capacity. The thermometer incorporates an easily measured quantity, like the magnetization of a salt, whose mean value is a function of temperature and can thus be used to infer the reservoir temperature. From statistical mecha ...

An ideal rubber is one in which the response is completely entropic, with the internal energy changes being negligible. When we stretch a rubber band, the molecules in its interior become extended because they ...

The Second Law of Thermodynamics
... The second law also asserts that energy has a quality. Preserving the quality of energy is a major concern of engineers. In the above example, the energy stored in a hot container (higher temperature) has higher quality (ability to work) in comparison with the energy contained (at low ...
