Temperature ? a term that we use daily as a matter of course, without being made alert to the physical correlations. But how is Trustworthy defined?
First perceives temperature within their environment purely subjectively. If we have been too warm or too cold, it is just a feeling, which might be different from person to person ? because not everyone gets cold at exactly the same speed. The word temperature ? or, better, the condition, that influences (among other activities) our state of mind ? is chatted about daily when we are discussing the expected temperature from the elements forecast with friends, acquaintances or colleagues.
Temperature
With the word temperature (from the Greek ?thermis? = warm), a particular thermal state of a body is described. Heat is really a measure of the energy of a body, which is generated by the random motion of its atoms or molecules in the body?s interior. Here, the temperature is the magnitude of circumstances which establishes the power content connected with other physical quantities (mass, heat capacity).
Temperature unit
The machine of temperature is the Kelvin. At a temperature of 0 K, all atoms or molecules inside a body are at rest ? all motion within the body is frozen. One describes this state because the absolute zero point. The Celsius temperature scale which is more common inside our latitudes defines the zero point as the freezing point of water, since this condition could be reproduced without great technical effort in past times.
Temperature measurement
Different physical properties are directly dependent on the temperature and therefore are used for temperature measurement, such as for example, for example:
the dependence of expansion on temperature
the change in electrical resistance with temperature
voltage generation depending on the temperature
temperature-dependent frequency fluctuations
changes in the wavelength of rays of a body, with regards to the temperature
