A thermocouple may be more useful than a regular lab thermometer if you want to measure fairly high temperatures. A disadvantage is that thermocouples may be subject to wear and may not be very accurate or precise. The thermocouple must be calibrated against a known standard before it is used for measurement.
that depends on what type of thermometer. The tube thermometer, the kind with a glass tube with a red liquid in it, uses a small amount of mercury in a very small tube. When the mercury is heated, it expands, pushing further up the tube, as it cools it contracts, going down the tube. A dial thermometer also works on expansion and contraction, but with a coil instead of mercury.
In my point of view , if you are a good student then you are a good worker . So, I can say education is very important , cause of this we can show innate abilities . But in work these abilities are hide .
The 1700s saw major scientific discoveries such as the thermometer, flush toilet and cotton gin. What was more significant than this was the advent and acceptance of scientific reasoning instead of relying on religion to explain the world. This resulted in further exploration about the laws of science.
Firstly, mercury has a freezing point of about -38Co. So a mercury thermometer cannot be used below this. Alcohols have a much lower freezing point, some around -100Co . Thus they are useful at much lower temperatures. Though alcohols are usually colourless, they can easily be dyed, usually red or blue. Alcohols however have lower boiling points, and this limits the maximum temperature at which they may be used.
There are multiple advantages of science and technology that are found in daily activities or objects. Technology and science has made living easier in many ways. One of the main advantages is that technology is able to do jobs that humans once had to do but in a much quicker manner. This has proven to be more time efficient and result in higher productivity in companies. Another advantage is how science and technology have improved transportation and communication. People are able to travel to local or far away locations at a more rapid pace than in previous years when the technologies didn't exist. Communication has improved to allow users to communicate in numerous ways instead of relying on postal mail or face to face meetings.
A thermometer which utilizes a gas(vapor) to react to temperature changes for an accurate reading. (Instead of a hazardous material such as a mercury filled thermometer.)
To measure temperature. A gauge can be used instead of a thermometer, and is generally used in industry where a thermometer might be too fragile
Alcohol, usually with a red dye in it
If you hold the bulb end, the thermometer will measure YOUR temperature instead of the temperature of the medium that you wish to measure.
no...........try it with a thermometer, just put ice in a cup, add salt then check the thermometer...........instead of going up, it will go down
There is nothing else in a mercury thermometer. However, some similar (glass tube-type) thermometers contain alcohol instead of mercury. Ray
What advantages did the Romans find in using a cross vault instead of a barrel vault?
What 3 advantages of using corn-based plastics instead of oil-based plastics?
When the thermometer is off, press and hold the power button until it gets to the "Lo" screen, then when it flashes, press the power button again until you see 'F' instead of "C".
Because the thermal expansion is higher from alcohol (ethanol) and then it's more precise.
Thats what i am asking but u ask me to answer it instead?!?!?!?!
