An electrical thermometer works by measuring changes in electrical resistance as temperature changes. This change in resistance is then converted into a temperature reading. The resistance of the sensor in the thermometer varies with temperature, allowing for accurate temperature measurements.

Explain how the common thermometer works by expansion?
A common thermometer works by using a liquid like mercury or colored alcohol that expands when heated and contracts when cooled. This expansion and contraction is used to measure temperature changes and is visualized through a scale on the thermometer, which gives a reading based on the level of liquid inside.
How do you tell how hot or cold something is?
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
How does an infrared thermometer work on water?
An infrared thermometer works on water by measuring the infrared radiation emitted by the water's surface. Water absorbs and emits infrared radiation, allowing the thermometer to detect the temperature without making direct contact with the water.
How does a liquid thermometer works?
A liquid thermometer works based on the principle of thermal expansion. As the temperature increases, the liquid inside the thermometer expands and rises in the narrow tube, indicating a higher temperature. Conversely, as the temperature decreases, the liquid contracts and falls, showing a lower temperature.
How do sixs thermometer works?
A six's thermometer works by using multiple mercury column thermometers with different temperature ranges to provide more accurate temperature readings. The thermometer tubes have different temperature ranges and are expanded or contracted by changes in temperature. By observing the position of the mercury in each tube, one can determine the temperature range in which the instrument is currently operating.
What is constant pressure gas thermometer?
the thermometer that works on constant pressure
How does a USB thermometer work?
A USB thermometer works in much the same way any digital thermometer works by measuring the temperature of the individual via contact with their skin or mouth. The USB thermometer is then able to be plugged into a computer via the USB to record and chart the findings.
How does a thermometor work?
i don't know how a thermometer works
What are the types of thermometer?
Celsius, Fahrenheit, and Kelvin.
How a laboratory thermometer work?
It works when the thermometer gains heat from the surroundings. When the thermometer gains heat from the surroundings, gradually Mercury expands and it points the accurate measurement of temperature.
What is the temperature that a resistance thermometer works best at?
0 to 100c
How can you tell the temperature in a weather system?
A thermometer works well for this.
How a liquid in glass thermometer works?
the heat makes it expand you see
What tools can you use to see how hot somthing is?
A thermometer works well for that.
How do you use a themometer?
stick the thermometer in your mouth and hold it under your tongue til it beeps if its an electrical one, if not then do the same but wait for about a minute or two. then check the thermometer
Different types of thermometers?
Celsius and Fahrenheit Thermometers Clinical Thermometers Ear (Tympanic) thermometers Pacifier Thermometers Underarm or Oral Thermometers Food Thermometers Outdoor Thermometers Mechanism of Different Types of Thermometers Mercury and Alcohol Thermometers Digital Thermometers Alcohol thermometer Beckmann differential thermometer Bi-metal mechanical thermometer Electrical resistance thermometer Galileo thermometer Infrared thermometer Liquid Crystal Thermometer Medical thermometer (e.g. oral thermometer, rectal thermometer, basal thermometer) Mercury-in-glass thermometer
Who invented platinum thermometer?
The platinum thermometer was invented by the German physicist Carl Wunderlich in the 19th century. He utilized the unique properties of platinum, such as its resistance to corrosion and consistent electrical resistance, to create a highly accurate thermometer.
