Fire Extinguisher Sublimation

The video tutorial explains the process of sublimation, where certain substances transition directly from a solid to a gas, bypassing the liquid stage. Using a carbon dioxide fire extinguisher, the experiment demonstrates this phenomenon by showing how solid CO2 turns into gas without becoming liquid. The video details the setup, execution, and scientific explanation of the experiment, highlighting the weak molecular bonds in solid CO2 that allow for sublimation. The tutorial concludes with a summary of the key concepts and observations from the experiment.
