Demonstrating Chemistry - Spectacular Experiments: Dry Ice - Sublimation

The video tutorial explores the properties of solid carbon dioxide (CO2), focusing on its sublimation process, where it transitions directly from a solid to a gas at -78 degrees Celsius. The instructor demonstrates this by adding solid CO2 to boiling water with food coloring, creating visible water vapor due to the temperature difference. The video also discusses the expansion of gas and the density of CO2 compared to air, highlighting its ability to drag water vapor downwards. The tutorial concludes with a summary of the learning outcomes, emphasizing the educational value of the experiments.
