No. Many substances melt and boil. Most of the elements, and many substances melt and boik without decomposition.
Freezing occurs when a substance's temperature is lowered and it changes from a liquid into a solid.
water
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 atoms movement is either more free (liquid to gas) or more restricted (liquid to solid)
When liquid becomes a solid it has to loose temperature. Because when a substance transforms into solid from liquid the atoms of that substance has to come closer to form the solid form.
Water. Water vapor, water liquid, and ice respectively
Minerals are solid substances that occur naturally in rocks and in the crust of the Earth. The type of mineral can vary depending on the area.
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.

Water
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 liquid to solid is called freezing.

A substance changes from a solid to a liquid at its melting point
Solid, liquid, gas, or plasma. A substance can occur in any one these states. All matter occurs in one of these 4 states. These are the 4 states of matter.
The atoms movement is either more free (liquid to gas) or more restricted (liquid to solid)
