A student observed a sample of an unknown material. His observations are shown in the box below:

The molecules of the substance are packed close together and have fixed positions in space relative to each other. It has resistance to deformation and change of volume. If enough force is applied, the matter can be permanently deformed.

Based on the observations provided, the student's sample is most likely categorized as a Solid.

The key observations include:

  • Molecules are packed close together and have fixed positions.
  • There is resistance to deformation and change of volume.
  • The material can be permanently deformed if enough force is applied.

These characteristics are typical of solids, as they have a definite shape and volume, unlike liquids and gases.
