What is temperature?

Temperature is a measure of hotness or coldness of a physical object with reference to some standard value. Similar to pressure or density, it is an intensive property. Meaning that it does not change as the amount of matter changes.


Degree Fahrenheit originally based its 0° value as the freezing temperature of a solution made from a mixture of water, ice, and ammonium chloride. But today, it's defined by two fixed points, the freezing point (32°) and the boiling point (212°) of water.


Degree Réaumur is a temperature scale for which the freezing and boiling points of water are defined as 0 and 80 degrees respectively. The Réaumur scale was used widely in Europe, particularly in France, Germany and Russia.
