The four states of matter are shown with these illustrations. 

Differentiate between these four states of matter by completing the chart. Click and drag each description to its correct state of matter.

• maintains a fixed volume and shape.

• Gas

• electrically conductive, produce magnetic fields and electric currents

• Liquid

• conforms to the shape of its container but retains a nearly constant volume independent of pressure

• Plasma

• has both variable volume and shape; expands to fill container.

• Solid
