helium and hydrogen gases
for a liquid to freeze , the attraction between the particles must overcome the motion of the particles.
As the distance decreases the attraction increases
The particles in the solid (solute) break apart and form links with the particles in the liquid (solvent). There are strong forces of attraction between the molecules and particles inside the solute. These forces keep the particles together and make the solute a solid because they attract the solute particles tightly together. There are also strong forces of attraction between the molecules and particles inside the solvent. These forces keep the particles together and make the solvent a liquid because they attract the solvent particles slightly together. There is also an attractive force between the solute and solvent particles. To break these forces and from a bond between the solute and solvent particles energy is needed. This energy is gained from heat (the process of dissolving is speeded up through heat.) In conclusion, the particles in a solute break apart of their attractive forces and form bonds with the solvent particles through the attraction between the solute and solvent particles and through the energy gained by heat.
No, electrons are never shared or transferred in a hydrogen bond. A hydrogen bond is just an attraction between partially positive particles and partially negative particles.
No. Watch what happens with talcum powder. When the particles between the solid are more cohesive than the attraction to water molecules, they will not be "wetted" and remain floating.
the particle in a solid overcome the strong attraction between them the particle in a solid overcome the strong attraction between them the particle in a solid overcome the strong attraction between them
the force of attraction get weaker the more the distance grows between magnetic fields
It is reduced.
The particle theory states that all particles are made of matter, these particles are in constant motion and there is a force of attraction between these particles. Solids have more closely packed particles and thse particles get looser as they progress through the states from liquid to gas. Therefore, moleculary, the molecules move faster and faster and appear farther and farther away from each other.

The particles start to give away and they break away from the attraction. This can be seen when boiling water, because when it boils there are bubbles and that is a sign that a new state is being made (gas) and that the particles are breaking away
Diffusion occurs - The particles of copper sulphate move between the particles iron because the particles are tiny and discrete.
