Parts of a Mercury Thermometer
Description:
A mercury thermometer is a traditional instrument used for measuring temperature. It consists of several distinct parts that work together to provide an accurate reading.
Parts:
- Glass Tube: The main body of the thermometer, often made of glass, which contains the mercury.
- Bulb: The bottom of the glass tube where mercury is stored.
- Mercury: A silvery liquid metal that expands or contracts with temperature changes, indicating the temperature on the scale.
- Scale: A measurement scale printed on the glass tube, often in Celsius or Fahrenheit, used to indicate the temperature.
- Capillary: A narrow, enclosed tube connecting the bulb and the scale, allowing the flow of mercury as temperature changes.
- Calibration Markings: Graduations or markings on the scale that indicate specific temperature points for accurate measurement.
- Reservoir: A chamber above the bulb that stores excess mercury when the thermometer is tilted or not in use.
- Holder: A protective case or structure that holds the thermometer, ensuring it remains stable during use.
Sample Sentences:
- The glass tube of a mercury thermometer holds the mercury inside.
- When the temperature rises, the mercury in the bulb of the thermometer expands, giving a higher reading on the scale.
- Make sure to read the scale of the mercury thermometer accurately to obtain precise temperature measurements.
- It is important to handle a mercury thermometer with care to avoid any breakage.
- The reservoir of the thermometer allows excess mercury to accumulate when not in use, preventing spills.
