To model how particles move as states of matter change, Jelani filled a clear box with as many marbles as the box would hold. Then he drew a picture of what the box looked like with the marbles in it.
Part B
Next, Jelani poured out about half of the marbles. Then he shook the box again. He could feel the marbles moving around more than when the box was full.
Finally, Jelani removed most of the remaining marbles and gave the box a final shake. This time, he could feel the marbles moving freely around the box.
Compared with the full box, which states of matter do these two models most closely represent? Explain.

Answer:

Hello ;)

Explanation:

ok part B there both similar bc The first pic shows that it has balls but not full and when he shook it he can feel the balls moving. So he look most of the balls out shows in the sec pic. When he shook  the sec box he can still feel the balls moving. The thing that are the same is they both have space for the balls to move
