Asolid sample of a compound a liquid sample of the same compound are each tested for elecrical conductivity. which test conclusion indicates that the compound is ionic?

A substance should contain charged particles that are free to move around in order to conduct electricity.

Ionic compounds contain an ocean of ions. They carry either positive or negative charges. Attractions between them hold them in a rigid lattice under the solid state. Those ions are unable to move. The ionic compound can't conduct electricity.

Melting the ionic compound will break the lattice. Those ions are now free to move to conduct electricity. Dissolving the compound in water will also free the ions. As a result, those solutions will also conduct electricity.

Conductivity under different states distinguishes between ionic compounds, molecular compounds, and metals.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
