The tube of a mercury thermometer has an inside diameter of `0.120`mm.The bulb has a voluem of `0.250cm^(3)`. How far will the thread of mercury move when the temperature changes from `10.0^(@)C` to `20.0^(@)C`? Take inot account expansion of the glass (Pyrex). b. Determined a formula for the length of the mercury column in terms of relavant variables.
