From the thermoscope to the digital thermometer: Termomegria work describes the evolution of temperature measurement in the last four centuries using thermometers based on the thermal expansion of liquids such as ethyl alcohol and mercury. The concept of temperature was strongly dependent on the researcher and there was no systematic temperature scale for universal use.

The precursor of the common thermometer was the thermoscopeprobably invented at the end of the XVIth century. In the XVIIIth century the instrument was greatly improved and several thermometric scales were proposed some of which have been in use until now. These scales were based on arbitrary points.

Mercury and ethyl alcohol sm the most employed thermometric fluids. In the XIXth century, the concept of absolute zero was a great advance in this field. The most important contribution during the XXth century was the establishment of international temperature scales.

An error occurred.

The design of the thermometer has been essentially the same along the last years, but many models were proposed for industrial and research purposes. Its association with the densimeter was of great importance for control of industrial chemical processes and also for teaching purposes in the past. Termometrai, there is a clear tendency to replace mercury-based thermometers by electronic digital models.

Thermochemistry is the natural relationship between temperature and chemistry. Basta pensar, por ex.

Sua “escala” estava dividida em “graus de calor”, segundo seus registros. Isto fazia com que este subisse no tubo. EmJoachin Dalence foi o primeiro a afirmar que eram precisos dois pontos fixos para se determinar uma escala 2,5. Assim, parece claro que determinar a “temperatura” de um corpo naquele tempo dependia do modo de cada um construir seu instrumento 2,3,7,8, Antes denenhuma escala era universalmente aceita.

Contudo, baseado nos trabalhos de Nicolas L. No ciclo de Carnot: Apesar disso, pesquisas recentes 18 empregando o condensado de Bose-Einstein permitiram atingir temperaturas da ordem de 4,5×10 K.
