temperature
Fluid behavior is determined to some extent by its temperature. A later section discusses the relationship between pressure and temperature in a gas.
temperature scales
A temperature scale is established by choosing two observable physical effects which are dependent upon temperature and assigning numerical values to them. The Fahrenheit and Celsius (previously known as Centigrade) scales use the freezing and boiling points of water as the two reference points:
The Celsius scale is most widely used in industry, but the Kelvin scale is important in determining the changes in gas pressure or volume with temperature.
