When you mix sugar into your coffee, the sugar molecules dissolve, indicating that they are soluble in water. This solubility occurs because the polar water molecules interact with the polar regions of the sugar molecules, breaking them apart and dispersing them throughout the liquid. This process demonstrates the ability of certain molecules to interact and form solutions, highlighting the nature of molecular interactions in liquids.
