Dissolve and join are opposites. Dissolve is for a solid to break down into a liquid, or for a body like a company or parliament to be formally ended. Join is to connect two things directly, or to become a member of a group. Dissolve breaks a body down until nothing stands; join connects things or adds a member.
One loosens a body apart; the other makes a connection. Dissolve, from dis- 'apart' and solvere 'to loosen', lets a solid lose its shape into a liquid, or ends a body so it no longer stands — a sugar cube in water, a company at its winding-up. Join, from jungere 'to yoke', connects two things directly or adds a person to a group. A partnership is dissolved; a new partner joins the firm. One unmakes or breaks down; the other links or brings in.
dissolve
To dissolve is for a solid to break apart into a liquid until it disappears into it — sugar dissolves in water — or, by extension, for something to fade out or be formally ended (a marriage, a company, a parliament is dissolved). From the Latin dissolvere, 'to loosen apart', from solvere 'to loosen', the root of solve and solvent. A substance dissolves when its particles separate and spread evenly through the liquid — the reverse of what happens when droplets coalesce. Governments dissolve; tension dissolves; a crowd can dissolve into laughter.
join
To join is to connect two things directly, or to become part of a group — join two pipes end to end, join a club, join hands. From the Latin iungere, 'to yoke'. At its simplest it makes one continuous thing out of two: where two roads meet, they can be joined into a single route. With people it means to enter or take up with — you join a team, join the queue, join forces. Unlike things that merge into one body, joined parts keep their own ends; they are linked, not dissolved.

Ask whether a body is broken down or a link is made. Dissolve loosens a body until nothing stands — a sugar cube losing its shape in water, a company wound up. Join connects two things, or adds a member — a fresh link closing two chains into one. If a body breaks down or is formally ended, that is dissolve; if two things are connected or someone joins, that is join.

Dissolve breaks a body down — a solid into liquid, or a company or parliament ended; join connects two things or adds a member. For organizations they are opposites: a partner joins a firm that stands, and the firm is dissolved when it ends. Note dissolve's everyday chemistry sense (sugar in water), which join does not touch.
