Which statement is TRUE about the arrangement of particles in a solid?

• The particles move freely in all directions.

• The particles are packed closely together in a fixed pattern.

• The particles are far apart and move randomly.

• The particles are loosely arranged and can slide past one another.

Which state of matter has the most energy?

• Solid

• Liquid

Why do liquids take the shape of their container?

• Because the particles are tightly packed and cannot move

• Because the particles slide past each other but stay close together

• Because the particles move in fixed positions

• Because the particles expand to fill the space completely
