Thermometer equilibrium
WebbTwo physical systems are in thermal equilibrium if there is no net flow of thermal energy between them when they are connected by a path permeable to heat. ... He considers two systems in thermal contact, one … There is an important distinction between thermal and thermodynamic equilibrium. According to Münster (1970), in states of thermodynamic equilibrium, the state variables of a system do not change at a measurable rate. Moreover, "The proviso 'at a measurable rate' implies that we can consider an equilibrium only with respect to specified processes and defined experimental conditions." Also, a state of thermodynamic equilibrium can be described by fewer macroscopic …

WebbThermal equilibrium is the state of the two objects after they have been in contact long enough. Relaxation time is how long it takes to reach thermal equilibrium. Footnote: Some people say this is when the temperature difference has reduced by a factor of . WebbA thermometer measures its own temperature.

WebbElectronic Thermometer. Electronic thermometers display either a predicted equilibrium temperature based on measurements taken over 15-30 seconds (in predictive mode) or an actual equilibrium temperature that is generally achieved in a minute or less (in continuous mode).
