What are some interesting facts about thermometers?

Question

please be specific

I think I know that hellogoo...

somthing interesting!!!!!!!!!!!!!1

Answer 1

Thermometers may have mercury in them.
The red ones are red alcohol.
Water can be used but requires a 12 foot tube.
A coil of metal can be used.
The freezing point of mercury is -40 on both F and C scales
The K and C scales are 273 degrees different, but the degrees are the same size
You can calibrate a themometer by putting it in ice water and marking it and then in boiling water and marking it
Expansion is the process that a thermometer uses

Answer 2

Interesting Facts About Thermometers

Answer 3

Thermometers are too broad a topic so I will just try to narrow them down to clinical thermometers.

Clinical thermometers measure your body temperature but they are unable to measure extreme temperatures. For example, putting such thermometers in a glass of ice cubes or a pot of boiling water will give you no results, not to measure dangerous!

This is because the mercury in thermometers are actually poisonous if the skin comes into contact with them. When a thermometer breaks and the mercury comes out, il resembles a silvery flexible solid. However, it is extremely dangerous, and any contact with skin would result in the mercury penetrating into the skin and it has adverse effects on one's health.

Well, a more safe alternative would be an alcohol thermomter. By the way, both thermomters vary with temperature (though not linearly-no such material is possible), although alcohol is safer and small amounts do not really pose any hazards to humans. However, it is less reactive to temperature changes, and that is why people still use mercury thermometers.

I hope I have answered your question.

instrument for measuring temperature. Galileo and Sanctorius devised thermometers consisting essentially of a bulb with a tubular projection, the open end of which was immersed in a liquid. Heating or cooling the bulb affected the height of the column of liquid in the tube, on which a scale was marked. Over a century later appeared the three thermometers now most widely used–the Fahrenheit, the centigrade (Celsius), and the Réaumur (used to some extent in parts of Europe). The first, invented by Fahrenheit c.1714 in Danzig, initiated the use of mercury as a heat-measuring medium; the thermometer of Réaumur, invented c.1730, used alcohol; the Celsius, invented by Anders Celsius at Uppsala (probably 1742) is now most used in laboratory work. The clinical thermometer is a small tubular instrument of rather thick glass. It consists essentially of a small vacuum tube of uniform bore closed at one end and connected at the other with a mercury chamber (either a bulb or a short tube of larger bore). A Celsius or a Fahrenheit scale (or both) is etched on the front of the thermometer; opposite this the glass is milky or semiopaque, to facilitate reading the temperature. When heat is applied, the mercury expands and rises from the chamber past a narrowed point and up the small tube. This narrowed point prevents the mercury from sinking back until shaking forces it down. A thermocouple can be used as a thermometer for measuring temperatures outside the range of liquid-in-glass thermometers. It is based on the thermoelectric effect occurring when the two junctions of a closed loop made of two different metals are at different temperatures

Answer 5

A mercury thermometer will freeze if it gets too cold! (below about -40 degrees). Also, there are some interesting stories about how Fahrenheit came up with his temperature scale. Some say he intended 100 degrees to be normal human body temperature, but he had a fever the day he did his thermometer calibration, so that's why actual body temperature is somewhat lower than 100.

Answer 6

To see if u r Hot? (fever)
Science experiments?
A whole PLANET could fit in the thermometer? (Mercury)

Answer 7

violates the gravitational law... when temperature increases the mercury level goes up!!!!!

Answer 8

the liquid inside is mercury. thats about it!
