Ice cream melting is going from a solid to a liquid, therefore it is in the melting process. Fog by dry ice is a solid going directly to a gas, therefore it is in the sublimation process. Frost forming is gas to solid, therefore it is the process of deposition. The mirror getting fogged up is the process of condensation because it is a gas becoming a liquid. Hair drying is the process of vaporization because it is a liquid to gas. Liquid glass hardening is the process of freezing because it is a liquid to a solid shift.
