Answer: Mercury is not an Insulator.
Mercury is a metal. All metals except mercury exist as solids at room temperature. It is a comparatively poor conductor of heat. In any alloy, if one of the metals is mercury, then the alloy is known as an amalgam. It is used in a device known as ‘mercury barometer’. It is a long glass tube closed at one end and filled with mercury that is inverted into a trough of mercury.
