Dissipate and unite are opposites. Dissipate is for something to scatter and fade away until nothing is left. Unite is to join parts or people into one for a shared cause. Dissipate reduces a thing to nothing; unite builds one body from many.
They end in opposite states. Dissipate, from dis- 'apart', takes a single thing — a mood, an energy, a crowd's resolve — and thins it until it has vanished. Unite, from Latin unus 'one', joins scattered people into one body around a cause. A shared threat unites a group's will; without it, that will can dissipate. One fades away to nothing; the other gathers into one.
dissipate
To dissipate is to scatter and fade until nothing is left: fog dissipates as the sun climbs, tension dissipates after an argument, energy dissipates as heat. Unlike disperse, where a thing spreads out but still exists somewhere, what dissipates loses itself completely — it thins into the air and is gone. From the Latin dissipare, 'to scatter', it can also mean to squander: a fortune may dissipate as surely as mist. Either way, something concentrated ends as nothing.
unite
To unite is for separate people, groups, or parts to come together and act as one — from the Latin unus, 'one'. A crisis unites a divided nation; scattered rebels unite behind a leader; two kingdoms unite under one crown. The word carries a charge of solidarity: those who unite often stay distinct yet stand together, as allied armies do when they unite against a common enemy. To unify is to make one cohesive whole; to unite is to join forces — to combine strength while keeping your own name.

Ask what is left at the end. Dissipate leaves nothing — a mood or a mist thinning until it is gone. Unite leaves one body — scattered figures joined hand in hand for a cause. If a single thing fades away to nothing, that is dissipate; if scattered people are gathered into one, that is unite.

Dissipate acts on a single thing that thins to nothing and is often intransitive; unite joins scattered people into one body for a purpose. They are opposites in outcome — one leaves nothing, the other one joined whole — and often meet in writing about a group's morale or resolve.
