The Changing Phases of Matter: Solid to Gas Phase Change

The video tutorial explains the process of sublimation, where solids transition directly to gas without becoming liquid. It uses snow and dry ice as examples to illustrate how sublimation occurs even at temperatures below freezing. The tutorial highlights that sublimation involves surface particles gaining enough energy to become gas, bypassing the liquid state.

Can you explain the process of sublimation in your own words?

What is the significance of the liquid state in the sublimation process?
