Sucrose is heated to higher temperatures before it gets caramelized. The reason has to be given for the caramelization of sugar only at high temperatures using the kinetic molecular theory. Concept Introduction: Kinetic molecular theory: This theory explains the laws that describe the behaviour of gases. It is based on five postulates. 1. A gas is composed of a large number of particles which are called molecules that are in constant random motion. 2. The distance between gas molecules is much greater than the size of molecules. Hence, the volume of the molecules is negligible. 3. Intermolecular interactions are so weak. Hence, they are also negligible. 4. Gas molecules collide with one another and with the walls of the container. These collisions are elastic collisions. They do not change the average kinetic energy of the molecules. 5. The average kinetic energy of the molecules depends only on the temperature.

Question

At certain pressures, ClF forms a solid that sublimes when heated. Using a few words and a simple diagram, explain what is happening when ClF sublimes upon heating. Be sure your answer describes the differences in the two states of matter.
