Concept:Intermolecular forces vary with the type of matter, so a claim of constant attraction is false.
Explanation:Particles of matter interact through forces that hold them together.
The magnitude of these forces is not the same for all substances.
It depends on the nature of the particles.
In solids, the attractive force is very strong, so particles remain closely packed.
In liquids, the force is moderate, allowing particles to slide past one another.
In gases, the force is very weak, letting particles move freely.
Because the strength changes with the kind of matter, the statement that it is constant is incorrect.
Answer:Option C is the incorrect statement.
