Describe the movement of particles within solids, liquids, and gases.
Paladinen [302]
Particles in solids move ever so slightly. They are not completely at rest, but since they are so packed together it’s difficult for them to move. That’s what makes a solid a solid. Particles in liquids slide and move past each other fairly quickly, and have space to move. Particles in gases are the most spread apart, and because of this, they move the quickest. Hope this helped.

1b. Broad leaf = Step 2

2b. Simple leaf = Step 7

7a. Leaf bases attached opposite each other on branch = Step 8

8b. Leaves not lobed = Step 9

9b. Leaves not heart shaped = Dogwood

The key is (1b,2b,7a,8b,9b)
