Aim • To calculate the SHC of water • To see how accurately I can measure a known quantity Research Question • Will the experiment carried out give us a good approximation of the SHC of water? Hypothesis • The result we will get as the SHC of water will not be exactly the same as the literature value‚ but will be a very close figure to the literature value of the SHC of water as there will be some limitations to our experiment. Variables Independent: temperature of water Dependent:

Aim To Find the Number of Moles of Water of Crystallisation in Copper (II) Sulphate salt. Introduction Water of crystallisation is the term given to the molecules of water that are used to build up a crystal lattice in some ionic compounds.In copper II sulphate the blue crystals would be impossible without using water molecules to act as ’scaffolding’ within the structure CuSO4.5H2O. When this is heated the water molecules are driven off and the blue crystals become a white powder. As most

Written task 1 A speech from an English Businessman‚ Michael Grospberry‚ who is a well known sociologist answering some questions that people from Latin schools asked about the introduction of English taught as a second language in every school at Latin America. What is the importance of knowing English? English is the second language most frequently spoken around the world after mandarin‚ this is considered a lingua franca because people that don’t have it as a native language speak this language

Oxidizing Magnesium AIM: To determine the empirical formula of MgO RAW DATA COLLECTED: Mass of Mg/g | Mass of O2/g | Mass of MgO/g | 0.12 | 0.07 | 0.19 | 0.15 | 0.08 | 0.23 | 0.16 | 0.08 | 0.24 | 0.19 | 0.11 | 0.30 | 0.21 | 0.11 | 0.32 | 0.23 | 0.09 | 0.32 | CONCLUSION: When a mass of magnesium is burnt in air‚ it combines with the oxygen molecules to form magnesium oxide. The graph doesn’t completely verify the empirical formula of magnesium oxide. There is a slight difference

DP Physics IA Thermal physics: Specific Heat Capacity of Metals Introduction: In this experiment we are going to measure the specific heat capacity of a unknown metal. To measure the specific heat capacity we will heat up the metal to certain temperature and release the metal in beaker filled with water. By knowing the mass and temperature of water filled in beaker‚ we will be able to calculate the specific capacity of unknown metal by change in temperature of beaker willed
