uses of mercury in glass thermometer

Mercury-in-glass thermometer 1 Mercury-in-glass thermometer Closeup of a maximum thermometer. Mercury is dangerous and banned or restricted in many fields in various countries. This prohibits the sale of measuring devices containing mercury, including thermometers and thermometers. Mercury is used mostly in thermometers because of the following properties: It is visible. Uses of thermometers. “In the LIG thermometer the thermally sensitive element is a liquid contained in a graduated glass envelope. It will then need to be taken in for repair before it can be used again. There are Harmful effects Chemicals Living Things that lurking behind the common daily life such as the mercury thermometers for determining the body, liquid, and vapor temperature from the households all the way to industrial usage. Mercury Thermometers are dangerous. Both have shown how technology has developed and come up with a solution. The volume of mercury changes slightly with temperature; the small change in volume drives the narrow mercury column a relatively long way up the tube. Mercury thermometers can be used to … The mercury is forced up through the constriction … The mercury filled bulb is connected to a glass tube which has a capillary tube inside it. Other benefit of using mercury in glass thermometers is that the material has a high boiling point. For example, if you measure the temperature of the air outside, you will know how to dress appropriately. In several states it is now illegal to sell mercury thermometers, and many countries have banned the use of mercury thermometers in hospitals and schools. It also has a high boiling point.This video is about: Why Mercury is Used in Glass Thermometer.. If you have a choice, it's better to use a thermometer without glass. Liquid in glass thermometers are the cheapest kind of thermometer, and are also easy to use. The rest of the tube may be a vacuum, or it may be filled with nitrogen. Best used to measure high temperatures, mercury thermometers are still widely used in meteorology and in high temperature places such as autoclaves, which are high-pressure vessels used to sterilize or process equipment. The thermometer also a very important feature to most machinery such as chemical tanks, vats, heating, and cooling equipment that make sure the factory production runs smoothly and safely. The operation of the mercury thermometer is simple to understand once all of the different parts are identified. In some cases, there are federal or state regulations that require the use of mercury-containing thermometers, although some alternatives such as digital thermometers and non-mercury liquid-in-glass thermometers are being used more frequently. Alcohol thermometers, infrared thermometers, mercury-in-glass thermometers, recording thermometers, thermistors, and Six's thermometers are used outside in areas which are well-exposed to the elements at various levels of the Earth's atmosphere and within the Earth's oceans is necessary within the fields of meteorology and climatology. Definition of mercury-in-glass thermometer in the Definitions.net dictionary. Prior to the use of mercury, alcohol was used, and it was Galileo Galilei, who in 1610 created a thermometer made of a glass tube that ends in a closed sphere. It is the route that allows the mercury to travel until reaching the temperature at which the target is in measurement and back to the bulb. Continue shaking until reading is below 35.6° C (96° F). Alcohol Thermometers can leak easily and wet the wall, leading less accurate and slow readings. The United States Environmental Protection Agency announced in 2010 that it will be working with industrial stakeholders and laboratories to phase out mercury-containing thermometers to reduce the release of mercury into the environment through spills, disposal and breakage.
