Question

a student groups the following materials together: copper wire brick wood rubber which property did the student most likely use to group the materials? a ability to float in water b physical state c flexibility d electrical conductivity

Explanation:

Copper wire, brick, wood, and rubber are all solids. This is a common physical - state property they share. The ability to float in water varies among them (copper wire sinks), flexibility also varies (brick is not flexible), and electrical conductivity varies (rubber is an insulator while copper is a conductor). So the most likely grouping property is physical state.

Answer:

B. Physical state
