frozen
When a solid is heated and changes to a liquid, the phase change is called melting.
Sublimation is the unique property in which a substance can go from a solid to a gas without becoming a liquid. Sublimation is a phase transition.
Freezing.
Freezing.
This is called a change in phase or a phase transition. It occurs when a substance transitions from one of the states of matter (solid, liquid, gas) to another due to changes in temperature or pressure.
Sublimination
The name for solid water is ice. It changes to a liquid when it melts.
Condensation
You may have your terms backward. Sublimation is the disappearance of the solid phase material in favor of the vapor phase material. No solid substance is formed during sublimation.
Sublimation
The process of gas turning directly into a solid is called deposition. This occurs when the gas vapor cools and transforms directly into a solid without passing through the liquid phase.
AnswerWhen a solid gains enough thermal energy, it will melt and become a liquid. When it has gained more thermal energy, it will evaporate or boil and become a gas. These are changes of state, and they are physical changes, and not chemical ones.
