The increasing order of forces of attraction between the particles of water, sugar, and oxygen is: oxygen < water < sugar. Explanation: Oxygen: As a gas, oxygen has the weakest intermolecular forces due to weak van der Waals forces. Water: While still having relatively weaker forces than sugar, water molecules have strong hydrogen bonds, which significantly increase the forces of attraction between them, allowing it to exist as a liquid at room temperature. Sugar: Sugar is a solid with strong intermolecular forces, including hydrogen bonding and numerous dipole-dipole interactions, leading to the highest forces of attraction among the three substances.
