Temperature ? a term that people use almost daily as a matter needless to say, without being made alert to the physical correlations. But how is the term temperature defined?
Accuse perceives temperature in their environment purely subjectively. If we are 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 word temperature ? or, better, the problem, that influences (among other things) our state of mind ? 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 really a measure of the energy of a body, which 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 energy content associated with other physical quantities (mass, heat capacity).
Temperature unit
The unit of temperature is the Kelvin. At Transform of 0 K, all atoms or molecules within 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 inside our latitudes defines the zero point as the freezing point of water, since this condition could be reproduced without great technical effort in past times.
Treasure 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 according to the temperature
temperature-dependent frequency fluctuations
changes in the wavelength of the radiation of a body, with respect to the temperature
