Why has the liquid inside a thermometer changed?
Because it used to use mercury which posed a threat to human health. They now use alcohol which is much safer.
Water is not used as barometric liquid?
Mercury is having a higher specific density ( about 13 times that of water) . So if we want to make a barometer using water it should be at least 13 times the length of mercury barometer that is about 11m so it is advisable to use mercury as a barometric liquid.
What is a non mercury thermometers?
A non-mercury thermometer is a thermometer that does not contain mercury as the temperature-sensing liquid. Instead, it may use alcohol, galinstan, or other materials to measure temperature. These alternatives are considered safer for environmental and health reasons compared to mercury thermometers.
Why is the bulb of a thermometer the most important part of a liquid thermometer?
you can use two main liquid substances in a bulb of a thermometer - the one i can remember -alchol-another one i am almost certain of -mercury- i am sorry if the later one is incorrect -if you do know the awnser i would appecheate if you conferm it for me .Remember you do not need to be a member or do anything to write an awnser .
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.
What liquid do they use in thermometres?
Mercury.
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).
What element is used in a barometer?
Barometers can use any liquid. A dense liquid that makes for a short column at room temperature, is mercury.
What liquid metal is use in the thermometer?
Mercury
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 common liquid can you use to test gold?
mercury
What element is a metal that is in the liquid phase at STP?
mercury and gallium are in form of liquid at room temperature
What are the two substances used in a liquid column thermometer?
The two substances used in a liquid column thermometer are mercury and alcohol. Mercury thermometers use mercury as the liquid inside the glass tube, while alcohol thermometers use colored alcohol such as ethanol or dyed ethanol.
What liquid is inside a filament transformer?
The predominate liquid used inside a filament transformer is mercury. Mercury is used to keep the transformer cool when under heavy use. Mercury is a cheap and long lasting liquid.
Where do humans make use of expansion?
thermometers (liquid mercury)
What is the name of the liquid in a thermometer?
The red liquid in a liquid-in-glass thermometer is mineral spirits or ethanol alcohol mixed with red dye. A grey or silver liquid inside the thermometer is mercury. Mercury thermometers are not used anymore due to the dangers associated with mercury.
Is Mercury a metal or a non metal?
Mercury is a metal , with all the properties of a metal except it is a liquid at room temperature.for ex when we use a thermometer we found mercury in liquid form. it is a metal
