Liquid Metal Used In Thermometers

In liquid in metal thermometers also referred to as liquid filled thermometers a liquid is used as a thermometric substance in the same way as in liquid in glass thermometers.

Liquid metal used in thermometers.

Most metals are good conductors of heat and they are solids at room temperature. And 2 some means of converting this. A thermometer has two important elements. A thermometer is a device that measures temperature or a temperature gradient the degree of hotness or coldness of an object.

1 a temperature sensor e g. Another substance used in glass thermometers is alcohol. The bulb of a mercury in glass thermometer or the pyrometric sensor in an infrared thermometer in which some change occurs with a change in temperature. Mercury can be used in thermometers.

Silver liquid indicates that the thermometer contains mercury while red liquid is alcohol to which red coloring has been added. Function the liquid in a thermometer typically stays in a bulb at the bottom of the device. Mercury is the only one in liquid state at room temperature. Because liquids expand as temperatures rise the.

It is also cheap to acquire and very accurate at measuring high temperatures. Hence the slightest change in temperature is notable when it s used in a thermometer. In addition mercury is the only metal that is a liquid at room temperature making it an attractive candidate. Lastly you do not need an external power source like a battery or electricity to run a mercury thermometer.

Although uncommon in modern thermometers a clear color indicates water.
