Temperature ? What actually is it?

Temperature ? a term that we use almost daily as a matter of course, 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 have been too warm or too cold, this is a feeling, which may be different from person to person ? because not everyone gets cold at exactly the same speed. The term temperature ? or, better, the problem, that influences (among other activities) our mind-set ? is discussed daily when we are discussing the expected temperature from the weather forecast with friends, acquaintances or colleagues.
Valor
With the term temperature (from the Greek ?thermis? = warm), a specific thermal state of a body is described. Heat is a measure of the power of a body, which is generated by the random motion of its atoms or molecules in the body?s interior. Here, Carefree 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 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 that is more common inside our latitudes defines the zero point because 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 with respect to the temperature
temperature-dependent frequency fluctuations
changes in the wavelength of rays of a body, depending on the temperature
