Mrs. Schumacher’s physics class has continued their hands-on learning and experimenting with the subject of Thermal Energy.
The students participated in a new project to demonstrate the melting and freezing curves of paraffin wax and lauric acid.
They started by heating a beaker of water to 700 C. They then submersed a test tube of the solidified wax or acid into the beaker and measured the temperature every ten seconds. The students continued this process until the substance was completely melted. The students then reversed the process by putting the test tubes into a bath of ice water and measuring the temperatures until the substance was completely solidified. Following this, the students inserted their data into a table, which then showed the first half of a heat curve for the substance. The experiments turned out well and the students were able to form an accurate heat curve.
