This change of phase is called freezing.
The process of a gas changing into a liquid is called condensation. The process of changing a solid into a gas is called sublimation.
Matter exists as either liquids, solids or gases, these are known as states of matter. The state of matter can change by heating or cooling. The process of changing a liquid to a solid is called freezing.
solidifying - its a changing state of matter
Vaporization is the process of a substance changing from a liquid to a gas, sublimation is the process of a substance changing directly from a solid to a gas, and condensation is the process of a gas changing to a liquid. Each process involves the transformation of matter between different states.
The process in which a solid changes to a liquid is called melting.
All matter has the ability to move from one state to another. The process of changing a liquid to a gas is called evaporation.
When a liquid changes to a gas, that can be done by means of a slow process called evaporation, or a fast process called boiling.
When water changes from a gas to a liquid it is still called water, but I don't think that was your question. The process of changing water, or any substance for that matter, from it gaseous state to it liquid state is called condensation,
The process of changing matter from the gaseous state to the liquid state is called condensing. A common example of condensation is steam from a hot shower condensing into water on the cooler bathroom mirror.
Melting is the change from solid to liquid.
The process of matter changing from liquid to gas state is called vaporization. This can happen through either evaporation, where molecules at the surface of the liquid gain enough energy to escape into the gas phase, or boiling, where the entire liquid is heated to its boiling point.
It is slow vapourization process. This process is called evaporation.
