Definition

Context #1 | Noun

measuring temperature

A thermometer is an instrument used to measure temperature. It typically consists of a glass tube containing a liquid, usually mercury or colored alcohol, which expands or contracts as the temperature changes. The measurement is read on a calibrated scale marked on the tube. Thermometers can be used in various applications, including meteorology, cooking, and medical diagnostics. Digital thermometers have also become popular for their speed and ease of use.

Synonyms

temp meter, temperature gauge, thermometric device.

Examples of usage

  • The meteorologist checked the thermometer to record today's high temperature.
  • I used a thermometer to ensure the chicken was cooked to the correct temperature.
  • The doctor took my temperature using a digital thermometer.
  • Make sure to read the thermometer carefully before taking a reading.

Interesting Facts

Science

  • Thermometers can be made of different materials like mercury, digital sensors, or alcohol in glass.
  • Mercury thermometers were widely used until concerns about mercuryโ€™s toxicity led to the use of alcohol and digital alternatives.
  • There are several types, including clinical thermometers for body temperature and meteorological thermometers for weather.

History

  • In the early days, temperature was measured using devices like the thermoscope, which didn't have a scale.
  • In 1714, Gabriel Fahrenheit invented a standardized thermometer that improved measurement accuracy.
  • By the mid-19th century, the Celsius scale became popularized, allowing for easier scientific communication.

Cultural Impact

Origin of 'thermometer'

Main points about word origin

  • The word comes from the Greek words 'thermo', meaning heat, and 'metron', meaning measure.
  • It was first used in the 17th century to describe devices that measured temperature.
  • The concept of measuring temperature dates back to ancient civilizations, but the modern thermometer was developed much later.

The word 'thermometer' originates from the Greek roots 'thermo-' meaning 'heat' and '-metron' meaning 'measure'. The concept of measuring temperature dates back to ancient civilizations, but the first true thermometer was invented in the early 17th century by Galileo Galilei. This early design measured temperature based on the expansion of air in a sealed tube. Later, the liquid thermometer was developed, greatly enhancing accuracy. Mercury thermometers became widely used in the 18th century, and their design was improved by various scientists over the years. The word 'thermometer' itself began to appear in English texts around the mid-1600s, symbolizing a significant advancement in the understanding and measurement of temperature in science and everyday life.
