Temperature ? a term that we use almost daily as a matter of course, without being made aware of the physical correlations. But how is Just Arrived defined?
Everybody perceives temperature in their environment purely subjectively. If we have been too warm or too cold, this can be a feeling, which might be different from individual to individual ? because not everyone gets cold at exactly the same speed. The term temperature ? or, better, the condition, that influences (among other things) our mind-set ? is discussed daily whenever we are discussing the expected temperature from the weather forecast with friends, acquaintances or colleagues.
Temperature
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, that is generated by the random motion of its atoms or molecules within the body?s interior. Here, the temperature may be 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 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 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 based on the temperature
temperature-dependent frequency fluctuations
changes in the wavelength of the radiation of a body, depending on the temperature
