For the thermometer, signal modification is accomplished by connecting the bulb to . the stem. . The inside diameter of the stem is very small relative to the diameter of the bulb, and although the change in mercury volume is small, this small change in volume produces a large change in length of the stem mercury column. .

(IB text - Ch 11; AP text - section 1.4 pgs. 10-13 and A10-A13). All measurements have some degree of . uncertainty. . Therefore, we need to give some indication of the reliability of measurements and the uncertainties in the results calculated from these measurements. . An Introduction to Uncertainty Analysis.

Scientists aim towards designing experiments that can give a “true value” from their measurements, but due to the limited precision in measuring devices, they often quote their results with some form of uncertainty..
