The three most common temperature scales are Fahrenheit, Celsius and Kelvin. The illustration below shows identical liquid filled thermometers. Each is calibrated with one of the three temperature scales. The Fahrenheit and Celsius scales show the boiling point for water at 212oF and 100oC.The freezing point for water is 32oF and 0oC. The size of the degrees is different.he Celsius and Kelvin scales have the same size degree, but have different 'zero' or starting points. The freezing point for water is 0oC and 273.15 in the Kelvin scale. Conversions between the Kelvin and Celsius require the addition or subtraction of 273.15.
In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature. Mercury thermometers are used in households, laboratory experiments, and industrial applications.
