Amalgamate and dissipate are opposites. Amalgamate is to merge several things — especially organizations — into one lasting combined body. Dissipate is to scatter and gradually fade until nothing is left. Amalgamate builds one whole that endures; dissipate thins a thing out until it vanishes.
One gathers into something that lasts; the other loses itself into nothing. Amalgamate, from amalgam (a mercury alloy), draws separate bodies into one whole that carries on under a single name. Dissipate, from dis- 'apart' and supare 'to throw', takes something concentrated — fog, heat, a fortune, a mood — and thins it out until it is simply gone. Several firms amalgamate into one company; a morning fog dissipates off the hills. One ends with a single standing body; the other ends with nothing at all.
amalgamate
To amalgamate is to combine several distinct things into a single larger whole — most often companies, institutions, or groups. The word comes from amalgam, an alloy of mercury with another metal, and it keeps that flavour: the parts bond into one body but often stay recognizable within it, the way stones stay visible in a wall. When firms amalgamate they dissolve into a new combined entity. It is a formal word, a close cousin of merge and consolidate, and the quiet opposite of forces that disperse.
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.

Ask what is left at the end. Amalgamate leaves one standing body where there were several — firms gathered under a single roof and name. Dissipate leaves nothing — a fog that thins and lifts off the hills until the air is clean and empty. If separate things build into one lasting whole, that is amalgamate; if a thing spreads out and fades until it is gone, that is dissipate.

Amalgamate is transitive and institutional, about bodies fusing into one; dissipate is usually intransitive and about something thinning to nothing, though it also means to squander (dissipate a fortune) and, of a person, to live dissolutely. The core contrast holds across all its senses: amalgamate concentrates into a lasting whole, while dissipate scatters until nothing usable remains.
