Could you ,my question 8 -9 and show your work

8. Picture B

Explanation:

There are 3 states of matter:

- Solid: in solids, atoms/molecules are bond together, so they are not free to move, they can just vibrate around their fixed positions. In solids, atoms/molecules are close and packed with each other

- Liquid: in liquids, atoms/molecules can move past each other, however there are still intermolecular forces that keep them close to each other

- Gas: in gases, atoms/molecules are totally free to move far from each other

In this case, atoms in the gas of a neon sign are represented by picture B, since there the atoms are very far from each other and free to move.

9. Picture C.

Explanation:

the picture that best represents a rock is picture C: in fact, we see that in picture C atoms are packed and close to each other, since it is a solid and atoms are bond to each other. So, picture C represents a solid, therefore it is the picture that best represents a rock.

the closer the planet is to the sun, the larger the gravity
