Probably a cheap one
A thermometer is considered an instrument, as it is a device used to measure temperature. It is not typically referred to as equipment, which usually implies a larger and more complex set of tools or machinery.
mercury is only used in a mercury battery
mercury was used for thermometers and baramoters
Mercury is not used in piping.
A mercury-in-glass thermometer, invented by German physicist Daniel Gabriel Fahrenheit, is a thermometer consisting of mercury in a glass tube. Calibrated marks on the tube allow the temperature to be read by the length of the mercury within the tube, which varies according to the heat given to it. To increase the sensitivity, there is usually a bulb of mercury at the end of the thermometer which contains most of the mercury; expansion and contraction of this volume of mercury is then amplified in the much narrower bore of the tube. The space above the mercury may be filled with nitrogen or it may be less than atmospheric pressure, which is normally known as a vacuum.
Mercury is an element and is very poisonous. It is not used as a drug.
Mercury thermometres aren't used much, because the mercury inside is poisones, But the reason that mercury used to be used is because Mercury expands rapidly, conserning the temperature e.g. if it gets hotter, the Mercury expands, so there is more of it. So, when you're measuring the tempurature, you're actually measuring how much mercury is there, therefore telling you what the temperature.
mercury is used in thermometers
Zinc is used in the reduction of mercury by forming an amalgam with mercury, which allows the mercury to be easily separated from other materials. This process helps to extract and purify mercury from its ores.
Mercury is highly poisonous and should not be used in milk production. The only place where mercury might be used in milk production is in mercury thermometers and where possible, these should be replaced with alcohol thermometers.
Water was initially used and later on alcohol was used.
