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 within their environment purely subjectively. If we are too warm or too cold, this can be a feeling, which might be different from individual to individual ? because not everyone gets cold at the same speed. The word temperature ? or, better, Cover-up , that influences (among other activities) our mind-set ? is discussed daily when we are discussing the expected temperature from the elements forecast with friends, acquaintances or colleagues.
Temperature
With the term 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 energy content associated with other physical quantities (mass, heat capacity).
Overnight of temperature is the Kelvin. At a temperature of 0 K, all atoms or molecules inside a body are in rest ? all motion in the body is frozen. One describes this state as the absolute zero point. The Celsius temperature scale which is more common in 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 dependent on the temperature and therefore are used for temperature measurement, such as, for example:
the dependence of expansion on temperature
the change in electrical resistance with temperature
voltage generation depending on temperature
temperature-dependent frequency fluctuations
changes in the wavelength of rays of a body, based on the temperature
