Las fases cambiantes de la materia: cambio de fase sólida a gaseosa

The video explains the process of sublimation, where solids turn directly into gas without becoming liquid. This phenomenon is observed in cold climates where snow disappears despite freezing temperatures. Another example is dry ice, which is solid carbon dioxide that sublimates at room temperature.

How does dry ice demonstrate sublimation?

What is dry ice and how does it change from solid to gas?
