No. Many substances melt and boil. Most of the elements, and many substances melt and boik without decomposition.
Yes. Water is a naturally occurring substance.
Water is the only substance that can be found naturally in all three states: solid (ice), liquid (water), and gas (water vapor).
If the density of a solid substance is greater than that of the liquid it is placed in, the solid substance will sink to the bottom of the liquid. This occurs because objects with higher density will displace an equal volume of the lower density liquid, causing the solid to sink.
This change in the state of matter (liquid to solid) is called freezing, not melting; it is a physical change, the chemical nature of the molecules is not changed.
When a substance melts, it changes from a solid state to a liquid state. This transition occurs when the substance absorbs enough heat energy to break free from its fixed, ordered solid structure and allows its molecules to move freely in a less structured liquid state.

Water. Water vapor, water liquid, and ice respectively
The process of solid to liquid is called melting. This occurs when a solid substance is heated to its melting point, at which the solid transitions into a liquid state.

Water is the only substance found naturally in the atmosphere as a solid (ice crystals in clouds), a liquid (raindrops), and a gas (water vapor).
Water is the only substance that can be found naturally in all three states: solid (ice), liquid (water), and gas (water vapor).
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.
Melting is the process in which a solid substance changes to a liquid state as it is heated. This change occurs when the substance's temperature reaches its melting point, at which the intermolecular forces holding the solid structure together weaken, and the solid turns into a liquid.
This change in the state of matter (liquid to solid) is called freezing, not melting; it is a physical change, the chemical nature of the molecules is not changed.

Caffeine occurs naturally as a white, crystalline solid. It is found in coffee beans, tea leaves, and cocoa beans.
