Different shapes of ice of same mass and density melt at different rates. This was proved by an experiment in which we noted the melting time of ice frozen in different shapes of medicine bottles. To carry out the experiment the apparatus we used included four medicine bottles with different diameters, water, glass, an ounce measure, freezer, ruler and clock…

When ice slid from each bottle we immediately measured the height and diameter of each ice piece. Then we placed each piece of ice on a wire grate and noted which piece of ice had come from which bottle. We placed the wire grate with pieces of ice on it away from the wind and waited for the ice to melt and noted the time with the stop watch. Meanwhile we calculated the surface area of the cylindrical ice pieces using the formula 2rh + 2r2 ; where r is the radius and h is the height of each piece of ice. We have used the formula of a cylinder to find the surface area of all pieces of ice because all pieces of ice frozen in different medicinal bottles had assumed almost the same cylindrical shape but they all had different diameters. We then repeated the whole experiment three times using the same medicine bottles and noted the time taken for ice pieces to melt in each trial as follows
Our experiment proved that the shape of a piece of ice affects its melting time. As can be seen in the table the greater the surface area of a piece of ice the smaller it's melting time. ...Download file to see next pagesRead More

Lab report of protein expression
Moreover, the GFP (Green Fluorescent Protein) gene usually exists naturally in the form of specialized photogenic cells found in the jellyfish Aquorea Victoria umbrella. This fluorescent protein can also be expressed in the bacteria, Escherichia coli. When the fluorescent protein gets exposed to U.V light source of long wave band, it produces a green light.

The Spectrochemical Series
This was done to determine the identity of each of these five cobalt complexes. Procedure Week 1 Complex B assigned by the instructor was prepared as follows: First 20ml acetone bottle was obtained then paced on ice water bath. Approximately 5 g cobalt salt was dissolved in distilled water (7 ml),this resulted to the formation of a purple solution.

Lab Research Report 2: Global Warming: Cause and Mitigation
Furthermore, for the natural climacteric trends, human beings did not play any part as it was purely an occurrence of nature that involved orbital variations of the sun, which instigated global warming. Following the initiation of natural warming, the greenhouse carbon dioxide gases are released, after which the gases combine with methane to increase the orbital warming.

The Effects of Temp & PH on Enzymes
This is because they have unique active sites into which only specific substrates can fit. Enzymes bind temporarily to one or more of the reactants of the reaction they catalyze and in doing so; they lower the amount of activation energy needed and thus speed up the reaction (Groves, 1997).
