used as a quick way of graphically demonstrating an image‚ idea or principle. Sketching is generally a prescribed part of the studies of art students. The term "sketch" has most often been applied to graphic work executed in a dry media such as graphite pencil‚ charcoal or pastel. It may also apply to drawings executed in pen and ink‚ ballpoint pen‚ water colour and oil paint. The latter two are generally referred to as "water colour sketches" and "oil sketches". A sculptor might model three-dimensional

Law of Refraction- by Aydar Z. Hypothesis: During investigation‚ student will calculate 2 sets of Angles of Incidence & Refraction. The Hypothesis is that 2 outer angles would have very similar values (1st angle of Incidence and 2nd angle of Refraction)‚ while 2 inner angles will also have similar values (2nd angle of Incidence and 1st angle of Refraction). This Hypothesis is based on earlier test investigations where outer angles were very similar in a range of 3 degrees and inner angles were very

of scattering peaks corresponding to the various d spacings in the crystal lattice. The positions and the intensities of the peaks are used for identifying the underlying structure (or phase) of the material. For example‚ the diffraction lines of graphite would be different from diamond even though they both are made of carbon atoms. This phase identification is important because the material properties are highly dependent on structure. Theory and Methodology The three-dimensional structure of

5.5 Candy Chromatography Background Information: Paper Chromatography is a separation tool in which pigment is put on a paper made of cellulose and water‚ and placed in a solvent‚ in this case isopropyl alcohol. Due to capillary action‚ the solvent crawls up the paper‚ separating the pigments. This technique is used to identify components of a mixture‚ even unknown ones‚ and can be used to isolate components into pure samples. Real world uses of this technique includes identifying certain biomolecules

Monomer is in liquid state and initiator dissolved in monomer is taken in a vessel and heated initially to poln temp. by a hot jacket to initiate the reaction. Monomer is added with constant agitation/ stirring for effective heat and mass transfer. Polymerisation reaction involves extensive bond formation in homogenous system and is exothermic.
