How mercury functions in a thermometer?
Mercury, like most substances, expands when it gets hotter and contracts when it gets colder. A mercury thermometer is designed so that the volume of the mercury can be accurately observed, as the mercury rises or falls in a marked column.
Why is Mercury used in thermometeres?
Mercury is a liquid over a wide range of temperature ( -39 to 357 degrees ) so it can be used in a variety of temperature ranges. Secondly it does not stick to the glass tubing of the thermometer so when the temperature falls ( i.e. after the reading is taken) all the mercury falls back into the reservoir. This ensures the accuracy of the mercury thermometer.
