Flammable gases are gases that have the tendency to explode (burst into flames) when they come in contact with the appropriate quantities of air, oxygen, or any suitable oxidant.

Devices that mix air or oxygen with flammable gasses cannot be used unless approved by an authorized or approved personnel.

Examples of flammable gases are hydrocarbons such as Propane, Acetylene, e.t.c.

Flammable gases are dangerous to humans and the environment and if they are not handled properly, can cause severe damages and even death.

During the preparation and usage of flammable gases, safety precautions should be properly enforced such as the wearing of appropriate safety gear and goggles.

Devices that mix air or oxygen with flammable gases cannot be used unless approved by an authorized or approved personnel.

Solid a is a very hard electrical insulator in solid as well as in molten state and melts at extremely high temperature. What ty

devlian [24]

This is covalent network type of solid.

For example, silicon dioxide (SiO₂) is covalent network solid with covalent bonding.

Covalent network solid is a chemical compound (or element) in which the atoms are bonded by covalent bonds in a continuous network extending throughout the material.

Silicon(IV) oxide has continuous three-dimensional network of SiO₂ units and diamond has sp3 hybridization.

This solids do not have free electrons so they are good insulators.

They have strong covalent bonds, so they melt at extremely high temperature.

Other examples are quartz, diamond, and silicon carbide.
