There are several types of thermometers in use in laboratories.
- The simplest is the liquid filled thermometer which converts the expansion of a liquid (Mercury or alcohol) into a temperature reading.
- Bimetallic thermometers use the differential expansion of metals at given temperatures to indicate atemperature.
- Thermocouple thermometers use the current generated by dissimiiar metals at a temperature to provide a input to an appropriately scaled electrical meter.
- Liquid crystal thermometers rely on the different melting points of solids to show temperature.
- Temperatures of objects may also be determined by measuring the infrared emissions from its surface
- Although not in use in labs there are also interesting thermometers using the density of liquids at different temperatures to allow calibrated floats to rise or sink

What is a dual probe thermometer?
this is a thermometer that can work twice as much as a normal thermometer or a thermometer that can check the temperature of two things at the same time
How does love thermometer work?
by heat
Will a thermometer work in the horziontal position?
Yes, it will.
Does synthetic coke show up in labrotory tox test?
If they're testing for it, sure.
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.
How does a thermometor work?
i don't know how a thermometer works
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 thermometer would be used to collect data over a twenty four hour period of time?
You can use the recording thermometer or the mercury thermometer, either one of those will work.
What three things should you always do when using acids or alkalis in the labrotory?
put safety glasses on
Why use equipment in a labrotory?
Cause lab equipment might be eaten if put somewhere else
What if where all just a brain in a jar in some evil scientists labrotory dreaming all of this?
..lol. plz answer
