Question

the particle theory of matter suggests...
o molecules of solids, liquids and gases are in constant motion
o molecules of solids do not move
o only molecules of gases move
o only molecules of liquids have random motion

Explanation:

The particle theory of matter states that molecules of solids, liquids, and gases are in constant motion. In solids, molecules vibrate in place; in liquids, they move more freely; and in gases, they move rapidly and randomly.

Answer:

molecules of solids, liquids and gases are in constant motion
