This change in the state of matter (liquid to solid) is called freezing; it is a physical change, the chemical nature of the molecules is not changed.
When a substance changes from a solid to a liquid and vice versa, its density changes.
Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
Melting point.
The physical change of a solid to a liquid at the melting point called melting.
The change between solid, liquid and gas is known as a change of state and is affected by the substance and its temperature. E.g. at room temperature water is liquid but a 0oc it becomes ice, a solid.
When a substance changes from liquid to solid is called freezing.
A substance changes from a solid to a liquid at its melting point
Freezing occurs when a substance's temperature is lowered and it changes from a liquid into a solid.
When a substance reaches its melting point it changes from solid to liquid. When a substance reaches its boiling point it changes from liquid to gas.
When a substance changes from a solid to a liquid and vice versa, its density changes.
You mean if a substance can go from solid to liquid? Of course, take the ice cubes out of the freezer and you'll see it happening. Do you mean that when such process occurs, does the substance changes? No, only the grouping and movement of particles in it.
The freezing point is when a liquid changes into a solid.
Vaporization is the process in which a substance changes from a liquid or solid state into a gas or vapor. This usually occurs when the substance is heated to its boiling point.
There are several names for when a solid changes to a liquid. Usually, melting of a solid occurs when heat is used near the solid and it changes it to a liquid.
Freezing.
The atoms movement is either more free (liquid to gas) or more restricted (liquid to solid)
