Why solids and liquids cannot be compressed?

• The particles are closely packed together and there are no empty spaces.

• The particles are far apart from one another and there are empty spaces.

• The particles are arranged in an orderly manner.

• The particles are not arranged in an orderly manner.

Why does solid has a fixed shape?

• The particles are held by very strong forces of attraction. They can only vibrate about their fixed position. Hence, they have an orderly arrangement.

• The particles are held by weak forces of attraction. They can move rapidly in all directions. Hence, they have an disorderly arrangement.

• The particles are held by strong forces of attraction. They can slide over one another. Hence, they have an disorderly arrangement.

The particles of solids ________________

• vibrate about their fixed postions

• are able to slide over each other

• move about freely at high speeds and in random direction

• do not move

Arrange the strength of the forces of attraction between the particles of solids, liquids and gases from the strongest to weakest

• (strongest) gases > liquids > solids (weakest)

• (strongest) solids > liquids > gases (weakest)

• (strongest) gases > solids > liquids (weakest)

• (strongest) solids > gases > liquids (weakest)

Which of the following best describes the arrangement of particles in a crystalline solid?

• Particles are arranged randomly

• Particles are arranged in a repeating pattern

• Particles are free to move around

• Particles are loosely packed

What property of solids allows them to maintain a fixed shape?

• High compressibility

• Strong intermolecular forces

• High kinetic energy

• Weak intermolecular forces
