They vary- most decompose into smaller units which may be molecules or atoms or free radicals. there is no hard and fast rule- usually we are talking of very high temperature gases.
It depends on the type of structure; simple covalent structures (like water) generally have low boiling points, while giant covalent structures (like diamond) have high boiling points.
Giant covalent structures, such as diamond and graphite, do not have a specific boiling point because their atoms are held together by strong covalent bonds that require high temperatures to break. These structures do not boil in the traditional sense like molecular substances but rather decompose or undergo phase transitions at extremely high temperatures.
No, water is not a giant covalent structure. Water molecules are held together by hydrogen bonds, which are much weaker than the covalent bonds typically found in giant covalent structures like diamond or graphite.
Ionic compounds can form giant structures, such as ionic lattices, due to the attraction between positively and negatively charged ions. Similarly, covalent compounds, like diamond or silicon dioxide, can form giant structures through the sharing of electrons between atoms. Metal compounds can also form giant structures, known as metallic lattices, due to the delocalization of electrons among metal atoms.
Metals have a sea of delocalized electrons that can move freely throughout the structure, allowing them to conduct electricity. In contrast, giant covalent structures like diamond and silicon have electrons localized in strong covalent bonds, making them insulators and unable to conduct electricity.
COVALENT
Yes, giant covalent structures can conduct electricity when molten because the atoms are free to move and carry charge. This allows for the formation of a continuous pathway for the flow of electricity. Examples of giant covalent structures that can conduct electricity when molten include graphite and silicon.

Silicon (like carbon) can form covalent bonds, it forms a giant molecule with the diamond structure. Silicon dioxide is also a giant structure with polar covalent bonds. Silica reacts with basic oxides to form silicates- and these are generally giant structures, polar covalent bonds again, that form a very large proportion of the minerals in the earths crust.

Substances that usually contain covalent bonds have a simple molecular structure. Examples include elements like oxygen and compounds like methane. Giant molecular structures are typically found in substances with strong covalent bonds, such as diamond and quartz.
No, wax contains very large molecules.
Indeed they can. A common example of Carbon covalently bonding with carbon is in what we refer to as Giant Covalent Structures, which are multiple of an atom bonded together in a set, lattice-like shape. Examples of giant covalent structures made from carbon are diamond where the atoms are arranged in a pyramid shape, and graphite, where they are arranged in flat layers.
No, wax is not a giant covalent structure. Wax is composed of long-chain hydrocarbons and does not have a complex molecular structure like giant covalent substances such as diamond or graphite.
