PROPERTIES OF SOLUTIONS A solution is a mixture of materials‚ one of which is usually a fluid. A fluid is a material that flows‚ such as a liquid or a gas. The fluid of a solution is usually the solvent. The material other than the solvent is the solute. We say that we dissolve the solute into the solvent. Some solutions are so common to us that we give them a unique name. A solution of water and sugar is called syrup. A solution of sodium chloride (common table salt) in water is called brine

Method 1.Firstly I will measure 20ml of Copper Sulphate solution (CuSO4) in a measuring cylinder‚ for precise accuracy‚ and then pour the solution into test tube. I will place the test tube into a beaker and insulate the test tube‚ for minimum heat loss. (As shown in the diagram above.) 2.Secondly I will measure the required amount of Zinc (Zn) on a weighing scale‚ again for precise accuracy. I will then measure the starting temperature using a thermometer. Next I will pour the Zinc into the test

is the temperature at which water changes phase from a liquid to a solid or vice versa. The freezing point describes the liquid to solid transition while the melting point is the temperature at which water goes from a solid (ice) to liquid water. In theory‚ the two temperatures would be the same‚ but liquids can be super cooled beyond their freezing points so that they don’t solidify until well below freezing point. Ordinarily the freezing point of water is 0° C or 32° F. The temperature may be lower

Original Composition While the cancerous fumes entered my lungs‚ the life threatening chemicals made me feel relaxingly calm‚ so I continued anyways. That was when I was still a kid‚ a fourteen year old nicotine addict‚ presently I am sixteen. I still remember those days in the past.

The cause of death was from second-hand

between informal organisational levels’; ‘within or between formal organisational levels’; and ‘between formal and informal organisational levels’. It is the essence of this deliberation to discuss the various causes of conflict at a school as an organisation. Furthermore‚ the paper will suggest solutions to the management and transformation of conflict in the school. The terms ‘conflict’ and ‘organisation’ are identified as some of the key terms and are therefore defined before the discussion unfolds
