I'm trying to figure out just how much mercury makes it into the measuring section of a mercury thermometer versus an alcohol thermometer, i'm sure it has to do with expansion coefficients but i do not know where to look.
for example, many mercury thermometers have 3ml of mercury in their base, if their length (excluding the mercury reservoir) is 100 mm, what is the width of the measuring tube? what is the volume?
i do not know if this matters, but say the maximum temperature is 43 C for one thermometer, 50C for another thermometer, and 100 C for the last thermometer.
and just to be more specific, when i say "width of measuring tube'' I mean the space which the mercury occupies, not the width of the glass structure which surrounds this empty/mercury filled space.
