How do liquid-filled thermometers measure temperature based on thermal expansion?
Look at an ordinary thermometer. You will see the mercury or achohol inside, and you will see regular degree markings along the thermometer. As the mercury or alchohol changes temperature, it expands and contracts.
What is thermometer made up of?
In this answer I m referring to the normal thermometers. Not the electronic thermometers. There is a very very thin capillary tube incide the thermometer which is filled with mercury and it has a bulb aT one end. When it touches a surface, the mercury expands, rises in the capillary and the temperature is shown.
How does the temperature effect the balloon filled with air?
the temperature affects the balloon filled with air because if it is too cold it can freeze it, and cause the balloon to pop
What type of barometer was invented first the aneroid or the mercury?
The first barometer that was invented was the MERCURY barometer. a mercury barometer consists of a glass tube open at the bottom end and partially filled with mercury. (:
What coils or uncoils with a change in temperature in a house thermostat?
These are called bi-metalic coils (two different metals stuck tightly together), which expand and contract at different rates when the temperature changes, thus coiling tighter or looser causing the glass tube filled with mercury to shift to the right or left to make or break the low voltage (~24volts usually) electrical connection, causing the air conditioner or heater to turn on and turn off when the temperature changes.
What is mercury filled glass tube that measures air pressure?
This is called a barometer.barometerBarometer
Is mercury used in food thermometer?
In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature.
What is the the name of the object a thin glass tubbed filled with liquid that measures temperature?
Thermometer
Which instrument is often filled with mercury or colored water or alcohol?
Thermometers are the instrument that is often filled with mercury, colored water, or alcohol. Most early thermometers were made with mercury.
What is an instrument that measures changes in air pressure using liquid mercury?
Any liquid can actually be use in a tube (barometer) to measure air pressure, but there are various advantages in using mercury for the purpose. 1. Mercury is a shiny liquid (a liquid metal) so it can be easily seen through the glass tube. Other liquid like water are transparent. 2. Mercury is very heavy. So only 76cms of it rises in the tube. Had you been using water for the purpose, you would need a glass tube as long as 55ft. 3. Mercury does not stick to the glass surface inside, so the reading obtained is much more accurate and precise. Remember: Water droplets stick to glass.

Define vapor pressure thermometer?
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.)
Name the metalic element which is liquid at room temperature and is used in thermometers?
Mercury, also called quicksilver, is a chemical element in the periodic table that has the symbol Hg and atomic number 80. A heavy, silvery, transition metal, mercury is one of five elements that are liquid at or near room temperature. Mercury is used in thermometers, barometers and other scientific apparatus, although the use of mercury in thermometers has been largely phased out in clinical and scientific environments (in favor of alcohol-filled, digital or thermistor-based replacements) due to concerns about the element's toxicity. Mercury, like lead, is a neurotoxin, and elevated blood mercury levels have led to retardation and deformities in children. ~Wikipedia
Why element mercury liquid at room temperature?
the metallic bonding is not very stong among the atoms due to larger atomic size and full filled 'd' orbitals in Hg....
What were thermometers once filled with?
I think that thermometers (liquid) were once filled with mercury. Xo, Smartiiz.
Why did they stop making mercurochrome?
It stained and was filled with mercury.
Why is alcohol red in colour in thermometer when alcohol is a colourless liquid?
Traditional thermometers are filled with red-dyed alcohol while others are filled with mercury which appears silver in color. Mercury thermometers aren't safe. When a mercury thermometer breaks on the floor mercury is released. Mercury is very toxic and venomous. One sole drop can kill you or make you very sick. Alcohol is dyed red to add more visibility. Otherwise it'll be very hard to read the temperature due to the alcohol's transparency.
