Place a few crystals of iodine in a dry test tube. Heat the tube and note the changes. Cool the tube. Observations: What happens when the tube is heated? What is this substance? Does any iodine melt? What is formed on cooling the tube? What is this process called? Define it. Name another substance that could undergo such a process.
