Which atoms and/or ions expand in all directions?


solid and liquid atoms

liquid and gaseous atoms

gaseous atoms and plasmic ions

plasmic ions and solid atoms

Verified Answer :

Gaseous atoms and plasmic ions expand in all directions.

Answer:

Gaseous atoms and plasmic ions

Explanation:

The atoms or ions in a solid state vibrate about their own fixed location upon heating. The atoms in solid state are tightly packed together and do not have space between them to expand in all direction. The atoms of liquid state are less tightly packed than that of the solid state but cannot expand in all directions due to their fixed volume. Ions/ atoms in gaseous and plasma state are present far apart from each other. These ions/atoms can move freely and expand in all directions since they are not held together with each other by interacting forces or bonds.
