A thermometer (from the Greek θερμός (thermo) meaning "warm" and meter, "to measure") is a device that measures temperature or temperature gradient using a variety of different principles. A thermometer has two important elements: the temperature sensor (e.g. the bulb on a Mercury thermometer) in which some physical change occurs with temperature, plus some means of converting this physical change into a value (e.g. the scale on a mercury thermometer). Thermometers increasingly use electronic means to provide a digital display or input to a computer.

∙ 14y agothermometers has changed as you can see old thermometer were not that reliable but now there are all kind of thermometer u have a lot of choices to choose from there is clinical thermometer, science thermometer and electronic thermometers

∙ 8y agoOther liquids are used in modern thermometers than the more hazardous mercury, simply because of the dangers of using mercury.

What liquid used to be in thermometers?
Most thermometers used to contain Mercury until it was found to be toxic.
What liquid used to be in most thermometers?
Most thermometers used to contain mercury until it was found to be toxic.
What liquid element is used in thermometers.?
Mercury (Atomic number 80) is still used in some thermometers.
What do thermometers do to the weather?
They do nothing to the weather. The liquid in them simply responds to the ambient temperature.
What is the phases of Mercury?
Mercury is a liquid. It can be found in thermometers.
What liquid mental is used for thermometers?
Mercury is used in thermometers.
What is the state of mercury in a thermometers?
Mercury in thermometers is in a liquid state, since mercury is liquid at room temperature.
How do thermometers with in liquid in glass measure temperature?
Such thermometers are based on the fact that the liquid expands when the temperature increases. That's what the thermometers measure.
What chemical is used in thermometers?
For non-electronic thermometers , you will either see a red liquid or a silver liquid. The 'Red liquid' is a coloured alcohol. The 'Silver liquid' is mercury.
Why liquid in glass thermometers are not suitable for industrial work?
Liquid in glass thermometers are fragile.For precise work, they need to be recalibrated frequently.
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 the principle of Mercury?

What were thermometers once filled with?
I think that thermometers (liquid) were once filled with mercury. Xo, Smartiiz.
What liquid meatal is used in thermometers?
Mercury
Liquid metal that was used in thermometers?
Mercury!
What is liquid use for?
As a temp. indicator in thermometers.
What is the basic principles of temperature measurement?
temperature is a measure of effect of heat energy. It tells us about the degree of hotness or coldness of a body. Increase in volume, change in specific resistance, emmision of electro magnetic waves (like Light) are the general effects of the temperature. Based on these principles temperatures are measured. Change in volume --- Liquid thermometers -- Mercury thermometers Change in resistance --- Resistance thermometers ---- digital thermometers Emmission of E/M waves --- Radiation thermometers --- Pyrometers RAMKI--India
