Here's a breakdown:

* Dissolving: The process where a solid substance (the solute) breaks down into individual particles and spreads evenly throughout a liquid (the solvent), forming a homogeneous mixture called a solution.

Examples:

* Sugar dissolving in water

* Salt dissolving in water

* Coffee grounds dissolving in hot water

Important Note: Not all solids dissolve in all liquids. The solubility of a solid in a liquid depends on factors like:

* The type of solid and liquid: Some solids are more soluble in certain liquids.

* Temperature: Higher temperatures usually increase solubility.

* Pressure: For gases dissolved in liquids, higher pressure increases solubility.
