    All fluids have its resistance to relative motion between surfaces and is called Viscosity. This property is about the friction between the particles of a fluid. A fluid that is forced in a tube has the liquid moving faster as it is closer the axis of the tube and slower when farther from it. 3.1.1 Dimensionless Parameters In analysis of convection heat transfer, it is convenient to convert to non-dimensional the governing equations and combine the variables, which makes the group of…

    Solution growth deposition This technique consists essentially of inserting the substrate into a solution containing hydrolysable metal compounds and pulling it out at a constant speed into an atmosphere containing water vapour. In this atmosphere, hydrolysis and condensation takes place. Finally the films are hardened by a high temperature cycle to form transparent metal oxides. Any hydrolysable compound including halides or nitrates but preferably metallo-organics are suitable…

    Mercury is highly toxic to a point where the exposure to less than a gram of liquid mercury can cause mercury poisoning. Mercury has low oxidation, the chemical element has little to no reaction when exposed to oxygen in the air. Mercury in general reacts with acids, the element reacts with some acids that are warm but has no affect to most cold acids. Mercury forms a chemical property called amalgam which is a liquid mercury mixed with metal alloy mixture used to fill cavities caused by tooth…

    them steep for 7 - 10 minutes with a watch glass on the top and the heat on low. Excessive heat can decompose caffeine so do not let the tea dry out. 2. Squeeze the tea bag against the side of the beaker with a stir rod to remove as much of the liquid as possible. Let the solution cool to room temperature. 3. Pour the tea into the separatory funnel. (Make sure that the stopcock is closed). Add about 10 to 20 ml of methylene chloride and shake gently. Vigorous shaking will lead to an…

    of some organic compound during filtration. Another reason for such a low percent recovery could be due to the drying agent. If the drying agent is added in large amounts it could lead to losing of the organic solvent by adsorption of the organic liquid. A better experimental result would show much higher percent recovery than the ones obtained. Obtaining a 100% recovery means that nothing was lost in the process. Also, the compound could have been impure and/or contaminated and so yielding…

    molecules are going to be less dense. When using only the ice cubes the molecules are going to be closer together which will increase the molecular count onto the soda. This should also help it cool the soda faster. Whereas, that molecules of a cold liquid mixed with ice cubes are more compact which makes it a more dense of a substance. This may give an advantage to the ice water. Because it is the most dense, it means the molecules are closer together. This also means that more molecules are…

    there. The volume of liquid in the beaker before the egg was placed in was 150 mL, and when the egg was taken out, the volume decreased to 130 mL. This proves that some of the distilled water that was in the beaker passed through the cell membrane and into the egg, which explains why the mass of the mass increased, while the volume of water decreased. The distilled water didn’t have any minerals or gunk that prevented it from going through the cell membrane easily, while the liquid that was in…
