Melting Point Determination and Thermometer Calibration Lab Background: The melting point of a substance‚ a solid in this case‚ signifies the temperature at which the first crystal starts to melt until the temperature at which the last crystal disappears is reached. That being said‚ melting points are expressed in ranges‚ am organic compound will have a sharp range depending on the purity of the compound. Impurity of an organic substance will register an abnormal melting point based on its

Experiment No : 5 Title : Concrete Cube Compressive Strength (7 days) Introduction : To determine the strength‚ maximum load can be applied and workability of concrete mixture. Theory : Hard concrete test were conducted at the age of 3‚ 7‚ 14‚ 21 and 28 days after curing(but we tested it for 7 days only). The concrete strength increases according to the age‚the mixture of its concrete design and the strength increment will continue for sometimes. Nevertheless‚ for most of the work‚ the

Question: How does the size of the cell affect its efficiency in exchanging substances through several ways‚ like diffusion? Aim: To plan and carry out an investigation to show the relationship between volume/Cm3‚ surface area‚ and diffusion using agar cubes measured in time/s; and to demonstrate‚ using diffusion‚ why the size of cells is limited‚ keeping the room temperature and pressure constant. Hypothesis: I expect to find that when the surface area to volume of a cell reaches a certain level‚ diffusion

How to solve a Rubik’s cube The purpose of this report is to inform the audience on how to solve a Rubik’s cube in three simple steps. Solving a Rubik’s cube can be difficult; however by solving one layer at a time‚ and knowing the correct algorithm to use for each desired move‚ makes solving a Rubik’s cube easier than it looks. Introduction Invented by mechanics in 1974. There are over 43 quintillion possible combinations for solving a Rubik’s cube. That is 43‚252‚003‚274‚489‚856‚000. (information-facts)
