between shape and diffusion rate Aim- To investigate the relationship between the shape of an object and the time taken for a substance to diffuse to its centre. Hypotheses- Part A) The 5x5x2.5mm block will turn clear first as the Surface area to volume ratio is high and the 10x10x10mm block will take the longest to completely diffuse the Acid to its centre. Part B) The flat‚ rectangular block will be the first to completely turn clear due to its high Surface Area/Volume Ratio. When measured‚ the

Financial Ratios: What They MeanIn assessing the significance of various financial data‚ managers often engage in ratio analysis‚ the process of determining and evaluating financial ratios. A financial ratio is a relationship that indicates something about a company’s activities‚ such as the ratio between the company’s current assets and current liabilities or between its accounts receivable and its annual sales. The basic source for these ratios is the company’s financial statements that contain

It will led the cells move randomly around to others. For this molecular movement‚ there are two results that might happen. Diffusion is one of them. Diffusion is the movement of molecules that between the high concentration and the low concentration

Just below the surface The story is written by Kate Nivison and takes place in a London suburb in an upper class environment (p. 41‚ l. 14) in modern time (p. 42‚ l. 23). It is a first person narrator so we sympathize with Indrani. Indrani: * Is an Indian woman (p. 42‚ l. 37) * Is education‚ but not highly educated * She is very bigoted (p. 42‚ p. 29-30) * She thinks the British people are xenophobic (the woman in the shop and the men from the council‚ p. 43‚ l. 15) *

Root Surface Caries Caries can affect any surface of the teeth. The most commonly seen caries are found on the crown of a tooth‚ above the cemento-enamel junction‚ it is also possible for caries to form on the root surface‚ below the cemento-enamel junction. Dental root caries has received a great deal of attention in the past few decades. A variety of different patients are at risk for root surface caries. Dentists use several methods of treatment. Root surface caries are also called cemental
