  • Coordination Number And Atomic Packing Factor
    2,045 words
    The materials used in solar hot water systems must be carefully chosen to ensure that the unit will be efficient but also affordable. The efficiency of the conversion of sunlight energy to heat energy of the water depends on the materials of construction and the efficiency of heat transfer of the materials. Solar hot water systems use the processes of conduction to transfer the heat absorbed from the sun to the water and convection to move water through their structure. This assignment discusses...
  • Ionic Compounds Conduct Electricity
    502 words
    Lab: Ionic and Covalent Compounds Pre-Lab 1. List the properties of ionic compounds. - Solids at room temperature. - Soluble in water. - Conduct electricity (while in solution). - Very high melting and boiling points. 2. List the properties of covalent compounds. - Solids, liquids, or gases at room temperature. - May or may not be soluble in water. - Most do not conduct electricity (except for acids) - Low melting and boiling points. 3. Give the name and formula for: a) 3 ionic compounds NaCl-So...
  • To Test Nine Substances For Conductivity
    752 words
    CHEMISTRY PRACTICAL REPORT Aim: To test nine substances for conductivity, solubility, appearance and melting point and find out if they were polar, non polar, continuous, ionic or metals. Method: 1) The first step is to collect your safety glasses and coat. 2) The next step is to collect your equipment you need nine substances, power pack, conductivity kit, test tubes, water, turps and Bunsen burner. 3) Next you start testing your substances you can start with any test. If you start with conduct...
  • Conductivity Of Water
    229 words
    The measure of the capacity of water to allow an electrical current is called conductivity. Conductivity in streams is affected by many factors such as the elements or compounds found in the water, the temperature of the water, the geology of the area, and the pollution in the water. Each of these factors affect the conductiity in some way. Many inorganic dissolved solids increase the conductivity of water. Examples of these include: chloride, nitrate, sulfate, phosphate, sodium, magnesium, calc...
  • Effect Of Three Variables On Water Conductivity
    1,830 words
    Abstract This experiment was designed to explore nature of water as it pertains to conductivity. It can be shown that the conductivity of a substance is directly related to the amount of dissolved salts in the substance, as salts are ions. One contributor to water conductivity, therefore, is soil, as it contains many minerals and other substances which, when dissolved in water, form ions. The experiment focused on the effect of three variables on water conductivity: the type of soil, the amount ...
  • Original Foul Water Sample
    584 words
    Purpose: The purpose of this lab is to purify as much foul water as possible by doing three procedures which are, oil water separation, sand filtration, and charcoal absorption / filtration. Procedure 1) Obtain approximately 100 mL (milliliters) of foul water from your teacher. Measure its volume precisely with a graduated cylinder; record the actual volume of the water sample (with units) in your data table. 2) Examine the properties of your sample: color, clarity, odor, and presence of oily or...
