BTEC Level 3 Applied Science Unit 2: Practical Scientific
Procedures and Techniques Learning Aim B: Undertake
calorimetry to study cooling curves
Introduction
The aim of this practical is that we are trying to contrast the rate of cooling between stearic
acid and paraffin wax. Both paraffin wax and stearic acid have the same forces of attraction
between them. The higher the temperature, the higher the kinetic energy of these
molecules and the faster they move around and as the molecules move slower, the forces
of attraction will be greater as they will be forming bonds. I will be calibrating the
thermometer as I will be check the temperature through boiling water, ice cold bath and
room temperature.
