the thermometer. 8. Rapidly heating the sample results in too high of a reading because the sample and aluminum bock are not at equilibrium with the mercury in the thermometer and this will result in a very high reading. 9. A mixed melting point analysis is preformed to determine the identity of an unknown sample. The unknown sample is placed in the heating apparatus and heated using a true (slow) melting point. Once the melting point of the unknown is determined‚ the known samples are mixed with

transmitting microwaves through soil samples. A relation between output power and soil moisture is obtained by analyzing the output power data for the soil samples. The relation is verified using known values of the moisture evaluated using gravimetric analysis. Experiments were conducted in the x- band frequency range of (8-12 GHz).Further an embedded system can be developed for the in-situ measurements of soil moisture.

CHEMISTRY DETERMINATION OF ENTHALPY CHANGE OF NEUTRALIZATION IA Criteria Assessed: DCP CE MS Introduction When an alkali neutralizes an acid‚ a salt and water are formed. Aqueous hydrogen ions (H+(aq)) from the acid react with the hydroxide ions (OH- (aq)) from alkali‚ forming water. The identity of salt will depend on the nature of the acid and alkali used. H+(aq) + OH- (aq) → H2O(L) The combination of H+ and OH- ions in this way releases energy. In this practical‚ the

Note: I couldn’t paste in pictures and diagrams so please excuse any large spaces. Planing my investigation 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

What is Beauty? Beauty can be seen differently by every single person in the world. Though people see beauty differently there are specific features the world universally sees as beautiful. There are a few scientific determinants of how attractive a person is and the society and culture a person lives in can contribute to how one person perceives beauty. To determine a person’s beauty it is up to someone to decide what the most important feature of a person is. A person may believe someone’s
