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.
What else can I help you with?
Why are gas thermometers more sensitive than liquid thermometers?
bc gas is easily compressed so it would have a more versitile range of measurement at least in our atmoshperic conditions. liquid not so easily compressed so very little pressure via mass w/gravity or heat would cause it to quickly jump between changes.
What liquid element is used in thermometers.?
Mercury (Atomic number 80) is still used in some thermometers.
What liquid used to be in most thermometers?
Most thermometers used to contain mercury until it was found to be toxic.
What liquid used to be in thermometers?
Most thermometers used to contain Mercury until it was found to be toxic.
What do thermometers do to the weather?
They do nothing to the weather. The liquid in them simply responds to the ambient temperature.
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 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.
What element is liquid metal used in the thermometers?
Mercury is the element commonly used in liquid-in-glass thermometers.
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.
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 are the two substance used in liquid column thermometers?
iodine and Mercury
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?
Mercury thermometers are based on the fact that materials (in this case, the liquid mercury) expand when heated.Mercury thermometers are based on the fact that materials (in this case, the liquid mercury) expand when heated.Mercury thermometers are based on the fact that materials (in this case, the liquid mercury) expand when heated.Mercury thermometers are based on the fact that materials (in this case, the liquid mercury) expand when heated.
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 were thermometers once filled with?
I think that thermometers (liquid) were once filled with mercury. Xo, Smartiiz.
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
