why is mercury used as insulators of heat
Answers
Explanation:
Mercury is use as Insulators of heat because,Mercury is the only one in liquid state at room temperature. It's used in thermometers because it has high coefficient of expansion. ... It also has a high boiling point which makes it very suitable to measure higher temperatures. Also, it has a shiny appearance and doesn't stick to the glass surface of glass.
it is a so-so conductor of electricity, but because it is a liquid at room temperature, it has several uses that make it specifically useful as a conductor. For example, if one needs an electrical connection to a rotating part (think of a rotating radar antenna), then it can find an application. If one needs a silently-operating tilt-sensitive switch, then a small blob of mercury sealed inside a glass bulb can bridge a pair of contacts in certain positions, but not in others. If built as a barometer or thermometer, the liquid mercury can raise and fall, bridging electrical contacts and signaling a given pressure or temperature..
