The document discusses the history and types of thermometers. Early thermoscopes were developed in the 16th century and Galileo invented the first water thermometer in 1593. In 1714, Gabriel Fahrenheit invented the first mercury thermometer. Traditional thermometers use liquid that expands with heat to measure temperatures in degrees Celsius or Fahrenheit. Common thermometers include liquid-in-glass, maximum, and minimum thermometers, as well as electrical resistance and radiometer thermometers.

Thermometer Mercury Rising<br />Early HistoryThe first thermometers were called thermoscopes and while several inventors invented a version of the thermoscope at the same time, Italian inventor Santorio, Santorio was the first inventor to put a numerical scale on the instrument.Galileo Galileiinvented a rudimentary water thermometer in 1593 which, for the first time, allowed temperature variations to be measured. In 1714, Gabriel Fahrenheit invented the first mercury thermometer<br />Thermometers measure air temperature. More specifically, this device measures the airs heat content. The idea of mercury rises actually refers to traditional thermometers, which use liquid to generate readings. Heat causes the liquid within the thermometer to expand and travel up and down the tube. Temperatures are measured in degrees Celsius or degrees Fahrenheit, depending on location.<br />Official thermometers used for keeping weather records, measure the temperature about 5 feet above the ground, usually within a specified shelter. This is important because wind and environmental effects, such as topography, or shade and shadows, can skew thermometer readings.<br />Types of thermometers:<br />Liquid-in-glass thermometer:glass tube filled with liquid (often mercury or alcohol) that expands/contracts with air temperature<br />maximum thermometer: usually are liquid-in-glass thermometers that record maximum observed temperature<br />minimum thermometer: usually are liquid-in-glass thermometers (use alcohol) that record minimum observed temperatures<br />Electrical resistance thermometers - measure temperature by measuring resistance in a wire<br />radiometer - measures radiation emitted by an object<br />
