NH₃

H₂

A compound can be a molecule, a giant covalent crystal, or an ionic crystal. The exact type of the compound depends the difference between electronegativities of its atoms.

All four compounds excepting for H₂ are ionic crystals.

the product of the pressure and volume is also constant

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
