What does dissolve mean definition for kids?

The word dissolve can mean: In chemistry, it is the act of solvation, when a solid is mixed into a liquid, creating a solution. Mixing salt into water is an example. Upon evaporation, the dissolved parts usually come out of solution and reform the solid.

What is dissolving ks3?

During dissolving, particles of solvent collide with particles of solute. They surround the particles of solute, gradually moving them away until the particles are evenly spread through the solvent.

How do things dissolve in water?

Because of its polarity and ability to form hydrogen bonds, water makes an excellent solvent, meaning that it can dissolve many different kinds of molecules.

What is the difference between dissolving and melting ks2?

Melting and dissolving are not the same. In melting only one substance is involved and the liquid and solid are the same material. Heat is needed for melting to occur. Dissolving involves two materials; the resulting solution is a mixture of both.

Solubility is the maximum concentration of a solute that can dissolve in a solvent at a given temperature. At the maximum concentration of solute, the solution is said to be saturated.

What causes dissolving?

Dissolving happens when the attraction between the particles of the solvent and solute are strong enough to overcome the attraction of the particles of the solute for one another.

How does dissolve happen?

Dissolving is when the solute breaks up from a larger crystal of molecules into much smaller groups or individual molecules. This break up is caused by coming into contact with the solvent. In the case of salt water, the water molecules break off salt molecules from the larger crystal lattice.
