Which thermometer is used to measure the temperature of burning match sick?
mercury
Why mercury is use instead of water in a thermometer?
when measure a very hot body with water inside the thermometer, the glass will break or the water will evaporate, similarly if we measure a cold body with the water again the water inside will freeze and we wont know thew correct measure
Can a mercury thermometer be used to measure temperature between 500 and 600?
No, you need another type of device as a thermocouple.
What is the name for the instrument used to measure temperature?
Most commonly, a thermometer.Related Information:Thermometers are used to measure the increase or decrease in the temperature of a system as it gains or loses internal energy.An alcohol-in-glass thermometer has been the most common personal instrument used to measure temperature. Mercury thermometers are still around but are no longer offered for sale. Today, digital devices are available that scan the forehead or ear. Some other devices used to measure temperature are:Radiation pyrometer, for extremely high temperatures;Glass thermometer: mercury or alcohol;Thermocouple;Thermistor (thermal resistor)Bimetallic strip;Bimetallic spiral;Platinum resistance thermometer (a resistance detector);Examples:A mercury in glass thermometer uses mercury liquid contained within its glass structure to be subjected to heat.the heat causes the mercury fluid to expand along the glass tubeand the total amount of expansion can be seen as a measurealong the accurate scale of indication.This is a direct indication of the effects of temperature.A more complex method of measuring temperature could be athermocouple measuring device.A thermocouple consists of 2 dissimilar types of metal materials in the form of wires , which are joined at 1 end by weld/ fusion.this single joined end is called the hot junction. The other end of the 2 wires are then terminated at separate junctions;as in a electronic terminal block. This end of the 2 wires can be called the cold junction.For most accurate temperature measure, I think temperature sensor is the first choice.
What is used to measure in degrees Celsius Fahrenheit or kelvin?
Electronic balance
What is Mercury thermometer use to measure?
A mercury thermometer is used to measure temperature.
What is the diffrerence between digital thermometer and mercury thermometer?
Digital thremometer is shows digit and run by electric or cells mercury thermometer is shows mercury up and down. when temperature low and down.
What is the difference between digital and mercury thermometer?
Digital thermometers measure electrical resistance and Mercury thermometers measure thermal expansion.
What would you measure temperature with?
A Mercury thermometer (but not a medical one!)
How many minutes do you take a rectal temperature?
If using a mercury thermometer - about a minute. A digital thermometer - a few seconds.
What is the raw experimental measurement made when using mercury thermometer?
Using a thermometer we can measure the temperature.
Which thermometer is used to measure the temperature of burning match sick?
mercury
What would you measure water temperature with?
A mercury thermometer (but not a medical one!)
Why can you not use a clinical thermometer to measure the temperature of a candle flame?
We cannot use a clinical thermometer to measure temperature of a candle flame because then the mercury will expand too much and the thermometer will explode.
Why is mercury is preferred in ordinary thermometers?
To measure the temperature calibrated in the thermometer. Mercury as a liquid reacts well to temperature changes. It expands as it gets warmer, so thermometers measure the rise of the mercury to measure temperature.
What is mercury contained in a tube used to measure air temperature called?
thermometer
Which element is used in the glass tube of a clinical thermometer to measure temperature?
mercury
