Display of d/ata and information/n You are a newly appointed technical assistant at a large chemical plant, Chemcalequip. As part of your induction period and to progress in your role, you have to demonstrate skills in a range of practical procedures and techniques. Part of your role is to ensure equipment is calibrated and equipment and chemicals are safety checked. You need to demonstrate your ability to use a calorimeter and associated equipment to obtain data to determine, analyse and evaluate the rate of cooling of substances. You will need to present evidence of your practical skills analysis and evaluation in a report. Task 1 Produce a report to evaluate the accuracy of your practical work in calorimetry. Ensure you have checked the calibration of a digital and liquid thermometer before use. Draw conclusions about any thermometer that may not be properly calibrated. You will need to demonstrate that you can correctly · select appropriate equipment and set it up. Provide a brief method. . Use the equipment safely to heat the solid substance(s) to above the melting point, measure temperature, at appropriate intervals as it cools and record the data in a table of your own design. · Use the data to construct cooling curves for two substances (stearic acid and paraffin wax.) Use the graphs you have constructed to accurately determine the rate of cooling at the start and demonstrate the ability to draw a tangent to the
