Advertisements
उत्तर
- Sugar is a solid; the forces of attraction between the particles of sugar are strong. Water is a liquid; the forces of attraction here are weaker than sugar. Oxygen is a gas; the forces of attraction are the weakest in gases.
- Thus, the increasing order of forces of attraction between the particles of water, sugar and oxygen is
- Oxygen < Water < Sugar.
