In this free lab students will use a simple calorimeter to determine the heat of crystallization (solidification) of a wax sample. This lab provides an excellent "visual and hands-on" lesson on the heat exchange that occurs during crystallization.
Suitable for physical science and chemistry students in grades 9-12.
Purpose of the Lab:
- To determine the heat of crystallization (solidification) of a wax sample from experimental data.
- To gain lab experience in using a calorimeter and in carrying out calculations used in calorimetry.
Materials:
- 16 x 125 mm test tube
- 250 mL Beaker
- Ring stand and ring
- Hot plate
- 100 mL Graduated cylinder
- Thermometer
- Styrofoam cup
- Safety goggles
- Lab apron
- Wax sample
- Balance
- Test tube tongs
