air during burning. Similarly‚ mercury would give off phlogiston when changed to ash. When Priestley heated this calx‚ he thought it reformed mercury by re-absorbing phlogiston from the surrounding air; this air which he collected‚ he therefore called ‘de-phlogisticated air’. According to this reasoning‚ mercury calx is mercury minus phlogiston and should‚ therefore‚ weigh less than mercury. Antoine Lavoisier repeated Priestley’s experiment and it showed that mercury calx actually weighed more than

Liquid-filled The traditional thermometer is a glass tube with a bulb at one end containing a liquid which expands in a uniform manner with temperature. The tube itself is narrow (capillary) and has calibration markings along it. The liquid is often mercury‚ but alcohol thermometers use a colored alcohol. Medically‚ a maximum thermometer is often used‚ which indicates the maximum temperature reached even after it is removed from the body. To use the thermometer‚ the bulb is placed in the location where

filled with mercury. The mercury rises in the cylinder when air pressure pushes down on the mercury. This is similar to a thermometer because the mercury in the thermometer rises and falls according to the temperature. When air pressure pushes down on the mercury in the container it will rise in the cylinder. The higher the air pressure the higher the mercury will rise in the cylinder. (Chris‚ Woodford) The cylinder will have marks to measure the mercury as it rises. We use mercury instead of

Mercury refining is a process in which one extracts mercury from its ore. To do this‚ you have to use very high heat to get the mercury above its boiling point. In a journal written by Nicholas A. Robins and Nicole A. Hagan called Mercury Production and Use in Colonial Andean Silver Production: Emissions and Health Implications they wrote‚ "Writing of the [mercury] refining process around 1590‚ the Jesuit José de Acosta described

The problem that the Attawapiskat tribe faces is that they have to find away to avoid mercury poisoning in the water that they drink‚ and the fish that they eat. The Attawapiskat people use the Attawapiskat River for hunting‚ fishing‚ and medicinal plants. The mercury is consumed on microscopic levels by bacteria and plankton
