Although glass beakers are common, beakers are also made from a variety of plastic resins (PMP, polystyrene, polypropylene, PFA, polymethylpentene, HDPE, ETFE, PTFE, and more). You may also find beakers made from stainless steel, quartz, and carbon. Griffin or Low ...
WebUncertainty An estimate attached to a measurement which characterises the range of values within which the true value is said to lie. It is written, for example, as 44.0 ± 0.4. … Web27 Aug 2024 · What is the uncertainty of a 1000 mL beaker? In the graduated cylinder shown in Figure 1, the mL graduations are marked and can be read with certainty. All graduated glassware is read with one estimated digit, so this measurement is recorded correctly to the nearest 0.1 mL, with an understood uncertainty of ± 0.1 mL.

Web17 Feb 2024 · It may have to do with the fact that it's a beaker, rather than some other kind of glassware. First, beakers are poor vessels for volumetric measurements due to their large diameter/height ratios. You have to add a lot of liquid, relatively speaking, in order to increase the height of the fill level by (say) a millimeter, and that means the uncertainty in … incense holder australiaWebCHEF11 LAB ONE REPORT 2024 Name: RUCI KALITONI Student ID: 20241376 TITLE: PRECISION AND SIGNIFICANT FIGURES AIM: The aim of this experiment is to take various measurements using equipment ’s in the lab, evaluating significant figures and doing some calculations with significant figures.
