A thermometer is an instrument to measure temperature. Mercury thermometer is a kind of thermometer that is often used by ordinary people. Mercury used in thermometers for temperature measuring instrument can be said muainya constant coefficients so that the change in volume due to the increase or decrease in temperature is almost always the same.
The equipment consists of a capillary tube using a glass material containing mercury at the bottom. For measurement purposes, this pipe is made in such a way that the vacuum. If the temperature rises, Mercury will expand upward to the top of the pipe and provide clues about the temperature around the measuring instrument in accordance with a scale that has been determined. Temperature scale most widely used all over the world is the Celsius scale with 0 points for the freezing point and boiling point 100 to point.
