Which statement about liquids is correct?

• They have a fixed shape and a fixed volume.

• They have a fixed shape but not a fixed volume.

• They have no fixed shape but they do have a fixed volume.

• They have no fixed shape and no fixed volume.

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

The diagram represent the arrangement of particles in ____________.

• gas

• liquid

• solid

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.
