It is generally called solidifying, but if it solidifies because of lower temperatures it is called freezing.
The change of state from a solid to a liquid is called melting.
Solids to Liquids (Melting) Liquids turning back into a Solid (Freezing) ((SCF))
The solid is called the solute. The resulting product is a solution.
When two liquids react to form a solid, it is called a precipitation reaction. This occurs when a solid substance, known as a precipitate, forms as a result of the reaction between the two liquids.
a precipitate
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.
Solids can be change into liquid by melting for example the ice. It will melt by just minutes in exposure of sunlight.. Liquid can be turned to gas by evaporating. Example a water can evaporate when heated..... :)
A solid substance that forms when two liquids are mixed is called a precipitate. This occurs when chemical reaction between the two liquids forms a new solid substance that is insoluble in the mixture.
phase change
Usually you freeze liquids so that they harden into solids.
A solid can change Into a liquid when it is heated Example- when heated solid chocolate, the chocolate changes into a liquid. A liquid Can change into a solid when it is cooled Example - If you leave juice in the freezer , the liquid changes into a solid.
