A common alternative is coloured alcohol. But a thermometer can be made of many things. You can have one made of metal that you stick into a piece of meat that you have been cooking, to see if the temperature is hot enough inside for the meat to have been cooked.
There are also industrial theremometers that are used in furnaces. There are many ways to measure temperature.
Whatever it is made of, a thermo-meter measures thermos, [Greek for heat].
Answer: The two properties you would want in a mercury thermometer are accuracy and precision. Accuracy is important because you want to know that it is recording the right temperature, and precision is important because it allows you to know the exact temperature to the extent of the gradations of that thermometer. Cherry flavor would be nice too! :)
Answer: It is used in the barometer because it is the densest liquid known, requiring only 33 inches of mercury to indicate atmospheric pressure. Water on the other hand would require 39 feet to indicate the same pressure.
It is used in thermometers for a different reason. The expansion of mercury is a stable amount. Meaning it changes in volume the same amount from 0 to 1 degrees as it does in volume from 100 to 101 degrees, making it a desirable fluid for scaling thermometers. Presently in the US it is illegal to manufacture these devices using mercury.
Answer: The mercury will expand and rise up the thermometer tube until it reaches the temperature of the air around it. When it stops expanding, it is the same temperature as the air, and therefore gives an accurate reading.
Answer: A lot and it is very detectable it shows up on an x-ray. It lodges in the brain and is the equivalent to shooting someone in the head. Also most glass thermometers contain alcohol not mercury. Seek counselling.
Answer: The invention is credited to several scientists, including Cornelis Drebbel, Robert Fludd, Galileo Galilei, and Santorio Santorio (Sanctorius of Padua), all of whom lived between 1550 and 1650. However, many of the devices were so-called thermoscopes, which indicated temperature change but did not quantify it.
The application of a scale is variously credited to Santorio or to Franscisco Sagredo (a friend of Galileo), between 1611 and 1614.
The first universal scale was designed by Daniel Gabriel Fahrenheit in 1724, followed by the scale of Anders Celsius in 1742.
Answer: A clinical thermometer will offer more precise calibrated readingsthan a mercury thermometer. The range of measurable temperaturediffers between a clinical and a mercury thermometer with themercury thermometer having the wider range.
Answer: If the bulb is red, blue, purple, green or any other color, it isnot a mercury thermometer. Mercury thermometers canbe used to determine body temperature (feverthermometers), liquid temperature, and vapor temperature.
Answer: No. But glassware is not a crystalline rigid material, and has somememory of recent thermal movement. Thermometers that have been calibrated at manufacture, will have acouple of tiny scratch marks along the scale, and the graduationsin between are interpolated. If you wish to calibrate athermometer, then do so at the triple point (close to 0 deg C), andat boiling point - 100 degree C. Since much of the stem of thethermometer has been at 100 degree C, straightaway after removingfrom the steam, the glass tube will shrink, and the reading willchange due to this, as well as the mercury column cooling. For a thermometer to be a precision measuring device, the bore hasto be accurately true, and this is not always the case. Ordinarymercury thermometers are seldom to be relied upon for better than 1degree C resolution. for further details
Answer: The temperature in a Mercury-based thermometer is read by the level of Mercury found in the thermometer. As Mercury heats up, it expands, therefore raising the level of the Mercury of which we see as a higher temperature. On the other end, as the temperature falls, the Mercury contracts and reads at a lower temperature.
Answer: It depends how much mercury you swallow and whether and how soon you get medical treatment. It is vary rare to die from swallowing mercury as it is not readily absorbed through the gastrointestinal tract.
