simply to know the temperature, if it wasn't coloured how would you know that the temp. is 37 c and not 100 c
The only way that the mass can change is if matter is added or taken away. The volume of a liquid can increase if heated, such as the liquid inside of a thermometer. The thermometer is sealed and no liquid gets in or out, so the mass of the liquid is unchanged. But when the temperature goes up, the liquid expands and is forced to go up the thermometer.
The narrower the bore the less liquid (mercury or alcohol) is required so the bulb containing the fluid will adjust more quickly to the temperature being measured. o.k well the narrower bore makes the liquid move slower up the thermometer so the accuracy is better ?????
Daniel Gabriel Fahrenheit invented the mercury thermometer in 1714.many inventers invented there own version of the thermometer but the mercury themometer i think most likely is just a regular thermometer you put in someones mouth under there toung. The regular inventor of the thermometer that you put in your mouth is some spanish named guy called Santorio but i dont reallt know his last name
i think it also depends on it's weight of course
0 to 100 i think

This is called the meniscus. It occurs because of surface tension between the liquid and the walls of the thermometer. When measuring water, you should read the temperature at the bottom of the meniscus for an accurate measurement.

A thermometer is an instrument used to measure temperature.Get me a thermometer I think he has a fever.I'm using a meat thermometer so I know exactly when the roast is done.The thermometer must be broken, it says 62 degrees, but it feels like 92 in here!
well it makes the art come to life i think it brightens the hole room sometimes its just beautiful when colored.

i think you mean a mercury theremometer
Words inside thermometer
I think your eyes are probably very pretty because of their unusual color.
i think red
no I don't think so.
Mercury is a metal so it will sink to the bottom of the pool where an alcohol will float. Actually, it's more likely that alcohol will simply disperse into the pool; low molecular weight alcohols are extremely soluble. A simpler way to tell is the color: mercury is silver and looks, well, metallic; alcohol in thermometers is generally colored either red or blue simply to make it easier to see. (A lot of people think mercury is red, but it isn't. Some mercury COMPOUNDS such as cinnabar are red, but those are not used in thermometers.) The fact that the liquid in the thermometer is metallic does not necessarily mean that it is mercury; it might be a gallium alloy. However, since mercury is toxic, if you're not sure it's probably safer to assume that it was mercury and treat the spill accordingly.
