Temperature ? a term that we use daily as a matter needless to say, without being made alert to the physical correlations. But how is Senseless defined?
Everybody perceives temperature in their environment purely subjectively. If we are too warm or too cold, this is a feeling, which might be different from individual to individual ? because not everyone gets cold at exactly the same speed. The word temperature ? or, better, the condition, that influences (among other things) 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 word temperature (from the Greek ? Off-the Record ? = warm), a particular 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, the temperature may be the magnitude of circumstances which establishes the energy content associated with other physical quantities (mass, heat capacity).
Temperature unit
The machine of temperature may be the Kelvin. At a temperature of 0 K, all atoms or molecules within 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 because the freezing point of water, since this problem could be reproduced without great technical effort in past times.
Temperature measurement
Different physical properties are directly influenced by the temperature and thus 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, with regards to the temperature
