Celsius Scale:
* Zero point: The freezing point of water is defined as 0 degrees Celsius (°C).
* Boiling point: The boiling point of water is defined as 100 °C.
* Divisions: The scale is divided into 100 equal intervals, hence the name "centigrade" (meaning "hundred steps").
How it works:
* Thermometric fluid: Most Celsius thermometers use a liquid, usually mercury or colored alcohol, that expands and contracts with temperature changes.
* Bulb: The liquid is contained in a bulb at the bottom of the thermometer.
* Stem: The liquid rises or falls within a sealed, graduated stem.
* Calibration: The stem is calibrated with markings corresponding to specific Celsius temperatures.
Types of Celsius Thermometers:
* Liquid-in-glass thermometers: The most common type, using a liquid to indicate temperature.
* Digital thermometers: Use electronic sensors to measure temperature and display it numerically.
* Infrared thermometers: Measure temperature by detecting infrared radiation emitted by objects.
Uses:
Celsius thermometers are used in various applications:
* Medicine: Measuring body temperature
* Science: Research and experiments
* Meteorology: Monitoring weather conditions
* Cooking: Determining food temperatures
* Industry: Monitoring and controlling temperatures in various processes
Important Note: While "Celsius" and "centigrade" are often used interchangeably, "Celsius" is the officially recognized term.
