What is the difference between alcohol thermometers and digital thermometers?
Alcohol thermometers use a liquid such as ethanol to measure temperature based on the expansion of the liquid, while digital thermometers use electronic sensors to detect temperature changes and provide a numerical reading. Digital thermometers tend to be more accurate and easier to read than alcohol thermometers.
What type of liquid do you use in a thermometer?
Typically, thermometers use either mercury or alcohol as the liquid inside the glass tube to measure temperature. Mercury thermometers are being phased out due to the toxicity of mercury, with alcohol thermometers being a safer alternative.
What is the coloured liquid used in thermometers?
Some times red coloured liquid is used but mostly gray coloured liquid is used.
What are the two substance used in liquid column thermometers?
iodine and Mercury
What chemical is used in thermometers?
Mercury is traditionally used in thermometers to measure temperature due to its high thermal expansion and conductivity properties. However, due to its toxic nature, many countries have shifted to safer alternatives such as alcohol or digital thermometers.
What is the liquid in a thermomether called?
Some thermometers use mercury, in these the liquid is silvery. Some thermometers use a red dyed alcohol solutioin.
What is liquid use for?
As a temp. indicator in thermometers.
What are 3 main different types of thermometers?
The three main types of thermometers are liquid-in-glass thermometers, digital thermometers, and infrared thermometers. Liquid-in-glass thermometers use a liquid like mercury or alcohol to measure temperature, digital thermometers provide a numeric temperature reading, and infrared thermometers measure temperature from a distance using infrared technology.
What liugiud metal is used in a thermomerter?
Many thermometers use the liquid metal mercury, Hg.
What is the difference between alcohol thermometers and digital thermometers?
Alcohol thermometers use a liquid such as ethanol to measure temperature based on the expansion of the liquid, while digital thermometers use electronic sensors to detect temperature changes and provide a numerical reading. Digital thermometers tend to be more accurate and easier to read than alcohol thermometers.
What liquid is used in some thermometers?
Achohol, usually. Older thermometers use mercury, but that is too dangerous.
What liquid is inside thermometers?
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).
Where do humans make use of expansion?
thermometers (liquid mercury)

What is liquid metal was used in thermometersr?
Mercury is a liquid metal used in thermometers. However, it becomes a solid at -37.9 F and it can cause mercury poisoning if ingested or inhaled. Therefore, most theremometers use ethyl-alcohol or a plastic strip covered with liquid crystals (called a liquid crystal thermometer).
