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.
One example is when water (liquid) is frozen and is turned into a solid (ice).
Everything - except hydrogen.
melting
fusion
-Solid and a liquid? -A liquid and a gas? -A solid and gas? from roop
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.
melting.
When a substance changes from liquid to solid is called freezing.
A substance changes from a solid to a liquid at its melting point
When a substance changes from a solid to a liquid and vice versa, its density changes.
The freezing point is when a liquid changes into a solid.
melting
The temperature at which a pure solid changes to a liquid is the substance's melting point.
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.
LIQUDIFCATION!!!!!!!! Change of phase; the process is called melting.
The temperature at which a pure solid changes to a liquid is the substance's melting point.
The solid changes into a liquid
The temperature at which a solid changes to a liquid is the melting point.
A substance changes from a solid to a liquid at the substance's melting point. This is a different temperature for every substance. For example, water (ice) melts at 0oC, whereas gold melts at 1,064oC.
