What is the difference between digital and mercury thermometer?
Digital thermometers measure electrical resistance and Mercury thermometers measure thermal expansion.
What is the purpose of mercury thermometers?
Mercury thermometers are used to measure temperature accurately. The expansion of mercury in the glass tube allows for easy visualization of temperature changes. However, due to the toxic nature of mercury, these thermometers are being phased out in favor of digital thermometers.
What instrument it used to measure temperature?
A thermometer is used to measure temperature. There are various types of thermometers such as digital thermometers, mercury thermometers, infrared thermometers, and thermocouples.
Which things depend on expansion?
Expansion can refer to various processes, but some common things that depend on expansion include thermometers, bridges, and concrete structures. Thermometers utilize the expansion of liquids to measure temperature, while bridges and concrete structures are designed to accommodate the expansion and contraction that occurs due to changes in temperature to prevent damage.
What instrument is used to measure temperature of a body?
A thermometer is used to measure the temperature of a body. There are various types of thermometers, such as digital thermometers, infrared thermometers, and mercury thermometers.
How do thermometers with in liquid in glass measure temperature?
Such thermometers are based on the fact that the liquid expands when the temperature increases. That's what the thermometers measure.

Are liquid filled thermometers digital devices?
Liquid filled thermometers are not digital devices. They rely on the expansion and contraction of a liquid to measure temperature, whereas digital devices use electronic sensors to measure and display temperature readings.
What is the difference between alcohol thermometers and digital thermometers?
Alcohol thermometers use a liquid such as ethanol to measure temperature based on the expansion of the liquid, while digital thermometers use electronic sensors to detect temperature changes and provide a numerical reading. Digital thermometers tend to be more accurate and easier to read than alcohol thermometers.
How do you measure the temperature clinical thermometers?
Clinical thermometers measure temperature by detecting changes in physical properties, such as the expansion of mercury or alcohol in glass thermometers, or through electronic sensors in digital thermometers. In glass thermometers, the liquid expands up a calibrated scale as temperature increases. Digital thermometers use thermistors or infrared sensors to convert temperature readings into digital displays. Each type of thermometer is designed for accuracy and ease of use, often providing readings in Celsius or Fahrenheit.
Which device is used to measure air temperature?
A thermometer is used to measure air temperature. Several types of thermometers can be used, such as liquid-in-glass thermometers, digital thermometers, and infrared thermometers.
Do thermometers measure in Celsius?
Thermometers can be calibrated to measure temperature in Celsius, Fahrenheit, or Kelvin. Most common thermometers used for everyday purposes usually measure temperature in Celsius.
WHAT IS THE TOOL USE TO MEASURE TEMPERATURE?
The tool used to measure temperature is called a thermometer. There are various types of thermometers, including digital thermometers, infrared thermometers, and traditional mercury or alcohol thermometers. These instruments work by measuring the expansion of a liquid, changes in electrical resistance, or infrared radiation emitted by an object. Each type is suited for different applications, such as medical, industrial, or environmental temperature measurements.
