Where did the temperature scales come from?
In 1742, Swedish astronomer Anders Celsius invented the Celsius scale, which measures temperature in degrees Celsius (°C). It has 0°C as the freezing point of water and 100°C as its boiling point. In 1848, Scottish physicist and engineer Lord Kelvin invented the Kelvin scale.
What are the three thermometer scales?
Temperature Scales. There are three temperature scales in use today, Fahrenheit, Celsius and Kelvin.
Who invented temperature scales?
Daniel Gabriel Fahrenheit
Daniel Gabriel Fahrenheit, the originator of the era of precision thermometry. He invented the mercury thermometer (first practical, accurate thermometer) and Fahrenheit scale (first standardized temperature scale to be widely used).
How did the thermometric scale get its name?
Throughout the centuries, countless thermometric scales have been devised for the quantitative measurement of temperatures. Many of these scales were abandoned long ago. The most widespread are described below. Named after the Swedish scientist Anders Celsius (1701-1744), this scale has become an international standard.
What are the names of the three temperature scales?
The three main temperature scales are Celsius, Fahrenheit, and Kelvin. Temperatures can be converted from one scale to another using temperature conversion equations. The three phases of water (ice, liquid water, and water vapor) can coexist at a single pressure and temperature known as the triple point.
How are temperature scales used in a thermometer?
Thermometers measure temperature according to well-defined scales of measurement. The three most common temperature scales are Fahrenheit, Celsius, and Kelvin. Temperature scales are created by identifying two reproducible temperatures. The freezing and boiling temperatures of water at standard atmospheric pressure are commonly used.
How did Anders Celsius come up with the thermometric scale?
In 1742, the Swedish astronomer Anders Celsius Suggested assigning the temperature from 0 ° C to the melting point of the ice and from 100 ° C to the boiling point of the water, and thus dividing the distance between the two points into one hundred equal intervals.
