important to have an understanding of the crystallochemical relationship between structures and temperature as having knowledge of it leads to a perfection in the structures formation. This is especially so as the structural parameters of FePO4 falls very closely to the values that are limited i.e. too high a pressure causing instability in the thermal conditions‚ thus it is in even greater importance that the amount of temperature used is studied in detail since it is a determinant of thermal stability

the Parthenon Marbles‚ also known as the Elgin Marbles‚ from Lord Elgin on July 11‚ 1816 through an Act of Parliament (1). The Parthenon marbles consist of 115 panels of frieze and 92 mesotopes of which the British Museum owns 56 panels of the frieze and 15 mesotopes. The museum also owns 17 pedimental figures‚ and thus houses about half of surviving sculptures of the Parthenon while the other half is in Athens (2). The legal circumstances surrounding Lord Elgin’s removal of the marbles is questionable

Biology GCSE Coursework: Osmosis in Potato Chips Skill Area P: Planning Aim: To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size. Hypothesis: Osmosis is defined as the net movement of water or any other solution’s molecules from a region in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially

Wing’s Chips‚ by Mavis Gallant‚ is a story that points out stereotypes amongst social classes in cultural groups in Canada. This story points out in particular the stereotype between the French and the English in Quebec. In the story‚ a young‚ English girl lives with her father in a French-Canadian town. Besides the fact that her father was an English man‚ he also didn’t conform to the norm of a working man. He was a painter and was not a catholic man. Near the end of the story‚ a powerful‚ French

For over 150 years the marbles of Greece have been placed in the British museum‚ they are recognized as the Elgin Marbles. The Elgin Marbles continue to be the main point of an ongoing debate that will basically determine the historical influence of an important culture. Some of the sculptures that were removed were the marble figures‚ metopes (sculptures in high relief) and friezes. To this day the Greek government has correctly requested the return of the Elgin Marbles a few times while the British

In Marble champ‚ By Gary soto‚ Lupe is a super shy girl who only is good at academic things and is not good at sports. Then she finds the sport marbles and now trains to be the best to win the marbles championship. She literally speaks in whispers as in she is very shy and does not really connect with people. But one thing Lupe really does good is believing in herself. “Believe you can and you’re halfway there.” Theodore roosevelt said. By believing in herself‚ Lupe practices‚ and she has tons of

How Acid Rain Affects Organisms in Aquatic Biomes Through the advancement of technology‚ the issue of the air surrounding the earth might have been one of the most often matters to be brought up and discussed among scientists and engineers. Acid rain is one of the more serious environmental problems and it is closely related to the air pollution. Nowadays‚ it has affected large part of US‚ Europe and Canada. People start to be concerned about acid rain since it is getting worse in the passed

Experiment A1: Kinetics of the Reaction between Acetone and Iodine The key aim of this experiment was to determine the rate equation for the acid-catalysed iodination of acetone and to hence consider the insinuations of the mechanism of the rate equation obtained. The stoichiometric equation for the reaction between iodine and acetone is below‚ followed by the rate equation (where x‚y‚z and k are the values to be obtained): I2 + CH3COCH3 CH3COCH2I + HI -d[I2]/dt = k [I2]x [CH3COCH3]y [H+]z

Investigation Into Temperature Sensors Introduction In this project I will be investigating how it is possible to use a temperature sensor to keep a greenhouse from changing temperature too much. This is intended to help plants live and grow in their optimum temperature. This will create a perfect temperature for the enzymes in the plants to work in‚ and therefore resulting in a maximum growth/production rate. This could be useful for gardeners who wish to grow plants as quickly as possible
