The relationship 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

backscatter X-ray is the right choice when compared to traditional X-rays or metal detectors. On December 27‚ 2006‚ the author‚ Thomas Frank‚whom is the aviation security correspondant for USA Today‚ wrote‚ "X-ray Tests Both Security‚ Privacy‚" and made valid points concerning the fear of radiation‚ how easily it finds metal guns and knives‚ and the provacy issue that surrounds X-ray technology (5). Throughout this essay Thomas Frank was able to write about the facts surrounding X-rays and keep

Aim:To discover what factors affect the rate of diffusion of potassium permanganate crystals in water. Statement:What will happen? How will room temperate solutions or heated solutions increase the rate of diffusion of the potassium crystals?Hypothesis:Heat will speed up the process of diffusion because heat will give out energy that will be able to speed up the process of spreading the potassium molecules.

There are explicit differences amongst emotivism and simple subjectivism. An important question arises when comparing both theories; does emotivism succeed in avoiding the objections to which simple subjectivism falls short? This paper will compare and contrast both theories‚ as well as identify any short comings of simple subjectivism‚ to which emotivism may succeed in answering. First and for most‚ simple subjectivism contends that when individuals make moral statements‚ they are just reflecting
