Question

give a reason why mercury is commonly used in the thermometers?

Answer 1

Elemental or metallic mercury is used in mercury thermometers and (in combination with silver and other metals) in dental amalgam. In China, dental amalgam was used to fill teeth over 1000 years ago (cited in Drexler 1998). Inorganic mercury, e.g. mercury chloride, has been used as a disinfectant.

The reason: Mercury released into the environment from a broken thermometer is highly poisonous. Pure mercury and its compounds can cause neurological problems and other ailments in people exposed to them. ... Federal and state authorities have lobbied since 2002 for bans on medical mercury thermometers.
