Temperature ? What actually is it?

Temperature ? a term that we use daily as a matter needless to say, without being made alert to the physical correlations. But how is the term temperature defined?
Everybody perceives temperature in their environment purely subjectively. If we are too warm or too cold, it is just a feeling, which might be different from person to person ? because not everyone gets cold at the same speed. The word temperature ? or, better, the condition, that influences (among other things) our mind-set ? is chatted about daily when we are discussing the expected temperature from the elements forecast with friends, acquaintances or colleagues.

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, that is generated by the random motion of its atoms or molecules in the body?s interior. Here, the temperature may be the magnitude of a state which establishes the power content associated with other physical quantities (mass, heat capacity).
Temperature unit
The unit of temperature is the Kelvin. At a temperature of 0 K, all atoms or molecules within a body are at rest ? all motion in the body is frozen. One describes this state because the absolute zero point. The Celsius temperature scale that is more common inside our latitudes defines the zero point as the freezing point of water, since this condition could possibly be reproduced without great technical effort in past times.
Temperature measurement
Different physical properties are directly influenced by the temperature and therefore are employed for temperature measurement, such as, 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 the radiation of a body, depending on temperature
