Watch the process of sublimation - the change of state from a solid to a gas - using dry ice, hot water, a balloon and lots of suspense.

Use this experiment to demonstrate sublimation, showing how solid air freshener changes directly from a solid to a gas. Includes kit list and safety instructions.

At room temperature, elemental iodine is a black-bluish solid. When heated, solid iodine sublimates and enters the gas phase. Iodine got its name from the G...

Place 2 grams of Iodine in a 500 mL Erlenmeyer flask, and set a watch glass with ice over the mouth of the flask. Place the flask on a hot plate, and turn on the hot plate so the flask is heated slowly. Purple …
