Chemistry Spec points covered Starter options Practical activity Teacher-led activity C1a States of matter C2.1 C2.2 C2.3 C2.4 Describe the arrangement, movement and the relative energy of particles in each of the three states of matter: solid, liquid and gas Recall the names used for the interconversions between the three states of matter, recognising that these are physical changes Explain the changes in arrangement, movement and energy of particles during these interconversions Predict the physical state of a substance under specified conditions, given suitable data (links to a Maths statement). In pairs, using paper or mini-whiteboards, students draw and write what they already know about the particles in the three states of matter. Groups feedback one or more of their answers to the class. Students record the temperature and appearance of a molten test substance. The temperature should decrease rapidly until the substance begins to solidify, at which point the temperature should remain constant. When the substance has solidified, its temperature should begin to decrease again. Equipment: Eye protection, stop clock, test tube rack. Boiling tube containing the molten test substance with a thermometer. Demonstrate the sublimation and deposition of iodine. Boiling water is not hot enough to melt or boil the iodine, so why does a vapour form and crystals re-form? Discuss the changes in arrangement, closeness and movement of the particles in the two state changes. Equipment Eye protection, iodine (maximum 0.25 g), stand, boss, clamp, round-bottomed flask, boiling tube, crushed ice, mineral wool, large beaker, kettle for hot water.
