What are three different sorts of thermomenters?
Mercury thermometer: uses the expansion of mercury to measure temperature. Digital thermometer: uses electronic sensors to quickly and accurately measure temperature. Infrared thermometer: measures temperature by detecting the infrared energy emitted by an object.
What common mistakes using a thermometer?
Common mistakes when using a thermometer include not waiting for the thermometer to reach a stable temperature reading, placing the thermometer in the wrong location (e.g. not under the tongue for oral thermometers), and not properly cleaning and storing the thermometer between uses.
What is the difference between a bulb thermometer and a electronic thermometer?
A bulb thermometer uses a liquid (usually mercury) inside a glass tube to measure temperature, while an electronic thermometer uses a sensor to detect temperature changes and provides a digital readout. Bulb thermometers are being phased out due to safety concerns with mercury, while electronic thermometers are more accurate and convenient to use.
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.
What is the diffrerence between digital thermometer and mercury thermometer?
A digital thermometer uses electronic sensors to measure temperature and displays the reading digitally, while a mercury thermometer uses a column of mercury to measure temperature and has a calibrated scale to indicate the temperature. Digital thermometers are often faster and more accurate than mercury thermometers, and are also safer since they do not contain mercury.

Different kinds of thermometer and their uses?
Different types of thermometer and their uses 1. liquid-in-glass thermometer: weather recording and laboratory uses. (Temperature sensor: laboratory uses.<--this may not count as one of the thermometers XD ) 2. infra-red thermometer: measuring body temperature. 3. rotary thermometer: measuring the temperature of ovens and freezers. 4. resistance thermometer: measuring temperatures from -200 degree C to 1000 degree C, e.g. engines and ovens, etc. 5. thermistor thermometer: measuring the temperature of human body and electrical appliances. 6. liquid crystal thermometer: measuring the temperature of human body and fish tanks. ( the color of liquid crystal changes with temperature.)
What is the advantage of bimetal thermometer?
A biometallic thermometer measures temperature. It uses a differential thermal expansion of metals that are bonded together into a strip. Another name for these thermometers is differential thermometer.
