Precision describes the closeness of results that have been obtained in exactly the same way while accuracy indicates the closeness of the measurement to its true value. This experiment was used to determine the accuracy and precision of different volumetric measuring devices‚ as well as determining the density of an unknown metal. This lab was to help understand the application to volumetric measurements. Part 1: First‚ the next-to-smallest beaker was cleaned‚ dried‚ and weighed on the scale

"TURMERIC: HOMEMADE WHITENING TOOTHPASTE" CHAPTER I Abstract: We are only recently becoming more aware of all the benefits of turmeric to our bodies. In addition to health benefits‚ turmeric also seems to have beauty benefits. Not only is it great for the skin‚ it also seems to whiten teeth! It is very skeptical‚ but the root plant we once thought to be only dyes to textiles can somewhat really make the teeth whiter and brighter! It sounds a little counter-intuitive to apply a rich yellow substance

Premium Density Volume Measurement
Lab No.1: density‚ accuracy and precision Aim: to determine the relative precision and accuracy of different glassware items by calculating the density of a known substance. Introduction: the density of a substance is its mass per unit volume. (where P-density‚ m- mass and v- volume). Different materials usually have different densities and densities vary according to the pressure‚ temperature and purity of a substance. When measuring‚ there is always a small uncertainty or error and therefore

Introduced in September 2002‚ Colgate’s ‘Simply White’ posed a threat to P&G’s dominant market share in the over- the-counter teeth whitening product category. Colgate emphasized that its product bleached teeth as effectively as P&G’s Crest Whitestrips and priced it at a significant 65% lower than Whitestrips which allowed it to gain almost 50% market share. Although concept tests done by P&G indicated that consumers perceived both products to be equal in terms of whitening levels‚ P&G’s internal
