What different types of thermometers exist?
Contributed by 1st grader Mackenzie and her mom Julie: There are circle thermometers which are like a clock and you read the numbers from left to right. There are stick thermometers that go under your tongue, your arm pit or other body parts. The numbers go from bottom to top. There are digital thermometers that can go in your ear, on your finger or other body parts. There are inside thermometers and outside thermometers to tell the general warmth/coolness of the space/environment. There are different scales - Fahrenheit and Celsius. Thermometers may be used to take a person's body temperature, to tell how warm/cold it is outside or in a room, to test whether food is cooked to a desired temperature to be safe. We hope we helped you.
Is mercury able to be heated up?
Yes, mercury can be heated up. Heat energy will cause mercury atoms to move more and spread out. This is actually how old thermometers would work. The higher the temperature, the more the particles would move and the more the liquid would expand. This would fill up the glass tube on the thermometer and make it possible to tell the temperature.
What form is tin found in compound or a pure element?
an element, symbol Sn ( from its old name Stannum)
Which element is used as rat poison and is found in the title of of the murder mystery ... and old lace?
Arsenic.
What element is also called quicksilver?
"Because it's silver in color, and runs quickly thru your fingers." Actually, this is not correct. Contrary to popular belief, it is not called quicksilver because it runs quickly through your fingers. The "silver" part is actually because of the colour but the "quick" part comes from the old English translation of the Latin word for living. The name means "living silver".

Where is mercury found around the home?
Old fashioned thermometers and in tuna.
Why is Mercury used in old thermometers?
Mercury was used in old thermometers because mercury expands when it reaches a certain temperature, so it was a really good "gauge". Now, they stopped making thermometers with mercury as the liquid since it was very poisonous. i hope you liked the answer!
When was the element Mercury found?
mercury was found in an old Egyptian tomb around 1500 BC meaning Before christ
What fluids can be used to measure temperature?
The most common are mercury and alcohol. Mercury is being phased out because it is toxic. Alcohol thermometers are used to replace the old mercury thermometers.
What are some facts about Mercury?
Mercury, the planet. Mercury is the second smallest planet in the solar system, the smallest is Pluto. It is the closest planet to the sun; it is known as an inner planet. Its speed helps pervent it from getting sucked into the sun. It orbits round the sun in about 88 earth days but takes 58 earth days to rotate once. Mercury has no atmosphere so it is a poor place to live. Mercury, the element Mercury is a highly toxic element. Humans exposed to mercury can die from mercury poisoning. All old oral and rectal thermometers contained a cylinder of mercury; kids at home and in chemistry class used to deliberately pour out mercury to 'play' with it because mercury always splits into small balls that join and split from the main body of mercury in whatever amount. At the time, the health risks of being exposed and touching mercury were not known as they are known today. Today, oral and rectal thermometers are digital and do not contain mercury. In the past, old thermometers were put in trash and trucked to landfills with all other garbage. This left small areas of contamination in the soil and ground water. Mercury must be disposed of as toxic waste; most health departments can take old thermometers for appropriate disposal. Industries that contaminate the waters can cause fish to carry high levels of mercury. If humans eat the contaminated fish, it can lead to mercury-related illnesses.
What liquid metal has been found in 3500 year old Egyptian tombs.?
A:Mercury (Hg) was the element which was discovered.
What liquid metal that used to be used in thermometers?
Mercury. Note: mercury is very toxic. If you find mercury (for example, if you break an old mercury thermometer), check with your local poison control center for instructions to dispose of it safely.
What is an element that is a very old poison?
an element that i think is a very old poison is mercury Antimony Arsenic Bismuth Mercury Copper Cadmium and Lead are all poisonous and used in old paint
What element is a liquid metal used in a thermometer?
Mercury is a liquid metal that is used in thermometers.
What element liquid metal that used to be used in thermometers?
Mercury
What is best known to be used in thermometers?
It depends on the thermometer. An old-style liquid thermometer might contain: * mercury (silvery) * alcohol (usually dyed red or blue for visibility) * an alloy of sodium and potassium (silvery) * an alloy of gallium, indium, and tin (silvery) * any of a number of other things depending on the temperature range to be measured Electronic thermometers contain a thermocouple plus electronics to turn the potential generated by the thermocouple into a temperature reading.
What element is a liquid in thermometers?
In the past, Mercury was used in ALL thermometers, oral or rectal for human use. But Mercury poses health risks. So they changed the internal workings to electronic components.As an historical point of view, when I grew up, all thermometers contained mercury enclosed in thin glass. If the thermometer was dropped, it could easily break. Mercury when spilled is attracted to it's own droplets. So although the mercury spilled out, it formed little round silver balls that could easily be pushed together, separated again, and pushed back together---all with one finger! Children delighted in "playing" with it, until the droplets rolled around in enough dust that they did not attract to each other as well. Then, we pushed the remaining balls onto a piece of paper and threw it into the regular garbage, which was then burned outdoors or in the coal furnace. After 1980s, they began making thermometers without mercury from fears about mercury toxicity and mercury poisoning. (But plenty of people now over 50 years old never experienced bad effects from playing with mercury droplets.)
