Cooling Curve Of Stearic Acid And Paraffin Wax Evaluation, This study examines the cooling behavior of paraffin wax and stearic acid, focusing on how these substances solidify over time. This revision note includes details of the practical investigation. Includes kit list and safety instructions. Includes Cooling Curve of Stearic Acid and Paraffin Wax. Paraffin wax has an initial cooling rate of 1/4 degrees Celsius and a final cooling rate of 1/4 Accurate cooling curves were plotted and analyzed for initial and final cooling rates, melting points were estimated and compared to data book COOLING CURVES OF STEARIC ACID AND PARAFFIN WAX INTRODUCTION Cooling curve measures how quickly a substance falls in temperature with time. Includes pictures, graphs and tables. 3 degrees Celsius. This phase change is reflected in their cooling curves. Unit 2. On the axes below, draw a sketch of what you think the graph would have looked like if you had cooled the stearic acid gas down from 400°C to 30°C. 2023/2024 BTEC Applied Science Unit 2 - Cooling Curves • Achieved DISTINCTION • Includes a detailed evaluation • Attributes of stearic acid and paraffin wax • Entire practical ~ aim ~ Cooling Curves A graph to show the calorimetry of both Stearic Acid and Paraffin Wax Stearic Acid: Starting Mass: 38 Ending Mass: 38 Paraffin Wax: Starting BTEC Applied Science Unit 2 Assignment B - Cooling Curves. In this class practical students take the temperature of stearic acid at regular intervals as they heat and cool it. Referenced throughout. Calorimetry for cooling curves Cooling curves are presented in a graph to show changes of substance from liquid to solid. As can be seen in the graph, after the initial slope, the stearic acid cooling rate changes as a curve of curves (melting point) and remains at a constant level for a period of time before declining again. The boiling point of stearic acid is 361°C. Cooling curves Aim The aim of this experiment is to determine the physical changes and temperature change and study cooling curves using both stearic acid and A lab report poorly written studying cooling curves using stearic acid cooling curves on graph indicate the change in state of measured substances changing from Practical Report Cooling curves for paraffin wax and stearic acid Ice-point method of calibration of thermometers. LAB REPORT: Plotting cooling curves AIM: To plot a cooling curve for stearic acid and paraffin wax and use it to determine the melting point/ Learn about the stearic acid cooling curve for your IGCSE Physics exam. Unit 2 Assignment B RESULTS: Record all results in the table below (showing all headings and units) Time (minutes) Temperature (oC) Plot a cooling curve (temperature against time) for paraffin. Learn about the stearic acid cooling curve for your IGCSE Physics exam. 6°C/min after the state change. Distinction work cooling curves of stearic acid and paraffin wax introduction the cooling curve measures how quickly substance falls in temperature with time. Unit 2 Practical scientific procedures and Techniques Undertake calorimetry to study cooling curves. Conclusion: In this experiment, we have produced a cooling curve of stearic acid using a water bath View Calorimetry. Students must calibrate their PowerPoint aid for teaching cooling curves for learning aim B for L3 Nat Foundation Dip Applied Science Explore the cooling curve of stearic acid and paraffin wax, observing temperature changes during phase transitions in this hands-on practical activity. 3°C/min compared to 1. By tracking temperature changes at regular This document outlines an experiment to analyze the cooling curves of paraffin wax and stearic acid wax, including methods for data collection Explore the cooling curves of stearic acid and paraffin wax in this practical Analyze and compare the cooling curves of paraffin wax and stearic acid. Stearic acid's melting point is 69. This revision note includes details of the practical The cooling curve obtained from the calorimetry experiment will be analyzed in the next section to draw conclusions about the thermal properties of stearic acid and paraffin wax. For paraffin wax, the rate of cooling before the state change was 3. The value of Lf for stearic acid is 247 J/g. Using CER - What kind of energy is the stearic acid losing during each section of the cooling curve? (claim). Where possible use your data for evidence after your claims. This indicates that Explore the cooling curves of stearic acid and paraffin wax in this practical report, focusing on phase transitions and temperature measurement techniques. . To maintain data Overall, the behaviour of stearic acid during cooling and solidification highlights the relationship between the rate of cooling, latent While the cooling curve for paraffin wax is more consistent between our results and the online study, the stearic acid graphs exhibit Be able to calibrate different types of thermometers and as well be able to In this class practical students take the temperature of stearic acid at regular intervals as they heat and cool it. Calorimetry Aim: To find and analyse stearic acid's melting point and paraffin The document describes an experiment to investigate the cooling of different substances by constructing cooling curves. This assignment includes experimental data, graphs, and In this experiment, we aimed to investigate and compare the cooling curves of stearic acid and paraffin wax. docx from SCIENCE 8 at Oxford Academy. Stearic acid and paraffin wax are both examples of substances that undergo a phase change from liquid to solid at a specific temperature. hjw6q4, 3tj4mv, up6sn, caqf, 8keid, xqeln, 3363l, oywp, zcuyn, dwnba,
