Purpose: Liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ. In this exercise I will work to determine the boiling point of a liquid and melting point of a solid. The boiling point of an element or a substance is the temperature at which the vapor pressure of the liquid equals the environmental pressure surrounding the liquid. The melting point of a solid is the temperature at which the vapor pressure of the solid and the liquid are equal. By understanding these concepts this helps to evaluate a compounds purity. Procedure: -Begin the experiment by reading all of the lab material. -Set out a clean organized workspace, clear of unnecessary debris or objects. -Ensure all appropriate safety equipment is safety equipment is set up. -Acquire all lab equipment necessary for the experiment including spoon, 2 small rubber bands, IPA, clean sheet, goggles, thermometer, test tube, burner stand, burner fuel, 100mL beaker, Acetamide crystals, and 2 closed- end capillary tubes. -The first test that will be completed to evaluate the boiling point of a liquid.
