Question

7 which statement about particles in solids, liquids, and gases is correct? choose three. all particles in matter move or vibrate. particles in liquids are in constant contact with each other. particles in solids get larger as they change to liquids. particles in gases are the farthest apart.

Explanation:

• According to the kinetic - molecular theory of matter, all particles in matter (solids, liquids, and gases) are in motion. In solids, they vibrate in place, in liquids they move more freely while still in contact, and in gases they move rapidly and are far apart.
• Particles in liquids are in constant contact as they flow.
• Gases have the most spread - out particles due to weak intermolecular forces.
• Particles do not change size when changing states; only their spacing and motion change.

Answer:

A. All particles in matter move or vibrate
B. Particles in liquids are in constant contact with each other
E. Particles in gases are the farthest apart
