All gasses that are not noble gases (well xenon and heaviei forms some interesting "patterns", if not truly molecules), or plasmas, are molecular gases.
When molecules in liquids and gases are heated they move faster
Helium, neon, and argon are the only elements that exist in nature as isolated atoms, due to their stable electronic configurations that do not readily form chemical bonds with other elements. These elements are known as noble gases for their inert nature.
after atoms and molecules of gases and liquids are heated, they sink?
Molecules of a gas are in permanent motion.
Hydrophobic molecules are those that repel water. Examples include hydrocarbons like fats, oils, and waxes, as well as nonpolar gases like nitrogen and oxygen. These molecules typically don't interact with water molecules due to their nonpolar nature.
Gases are substances with very weak bonds between molecules.
The observation about gases that proved molecules can move is their compressibility. This is further corroborated by the Brownian Motion theory.
I am pretty sure that that refers to gases that appear in nature.
It is assumed that Ideal Gases have negligible intermolecular forces and that the molecules' actualphysical volume is negligible. Real Gases have the molecules closer together so that intermolecular forces and molecules' physical volumes are no longer negligible. High pressures and low temperatures tend to produce deviation from Ideal Gas Law and Ideal Gas behavior.
Gases that are made up of only two atoms that can be both of the same or of different elements. Hydrogen, oxygen, nitrogen, bromine, chlorine, iodine, and fluorine are seven common gases that exist as diatomic molecules of the same element. However there are still examples of diatomic molecules that are made up of non- identical atoms such as carbon monoxide, hydrogen chloride and nitric oxide.
the reason there are no gases in mercury the molecules moves fast at high temperature
All gases have same kinetic energy of molecules at same conditions.
