Which of the following is/are incorrect?

• A. (1), (3), (4), (6)
• B. (2), (5), (3), (4)
• C. (1), (5), (6), (8)
• D. (2), (3), (5), (8)

Answer 1

The correct option is C

(1), (5), (6), (8)

Order of interparticle distance (distance between the particles) in different fundamental states of matter is Solids < Liquids < Gases.

Order of force of attraction in different fundamental states of matter is Gases < Liquids < Solids.

Incorrect options are

(1):- Interparticle distance (distance between the particles) increases if solid converts to liquids

(5):- Movement of particles increases, when liquid changes to gas because as the force of attraction between the particles in gases is less than liquids and distance between the particles, is much more than liquids so they have more freedom of movement.

(6):- Movement of particles decreases, when gas changes to the solid.

(8):- Attraction between the particles decreases when liquid changes to gas and that's why interparticle distance in gases is much more than liquids.
