(a) The tube of a mercury thermometer has an inside diameter of 0.140 mm. The bulb has a volume of 0.255 cm3. How far will the thread of mercury move when the temperature changes from 11.5°C to 33.0°C? Take into account expansion of the Pyrex glass. (b) Determine a formula for the change in length of the mercury column in terms of relevant variables. Ignore tube volume compared to bulb volume.

Solution 21PIntroductionPressure exerted by a fluid at a depth of h from the fluid surface is given by P = hdg , whered is the density of the fluid and g is acceleration due to gravity.SolutionWhen you stand up, your brain rises 40 cm above your heart.So, height h = 40 cmh = 0.4 m = 1060 kg/m 3Therefore, change in pressure due to this height is p = 0.4 m × 1060...
