When it comes to thermometers, mercury is a good choice. Explain.
When mercury is heated to room temperature, it turns into a liquid and has the highest coefficient of expansion of any element. Because of this, even the slightest variation in temperature can have a significant impact on the environment. Defined by its boiling point, mercury can also be used to measure very high temperatures. Because mercury does not adhere to the glass surface and has a shiny look, it is also used in thermometers.
