Dissipate and scatter both spread things apart, with a difference in what is left. Dissipate is to scatter and gradually fade until nothing remains. Scatter is to throw or send things in different directions so they spread out irregularly, but the things themselves remain. Dissipate fades to nothing; scatter flings apart but the things stay.
Both spread things out, but scatter leaves them and dissipate loses them. Dissipate, from dis- 'apart' and supare 'to throw', thins something out until it is gone — fog, heat, tension. Scatter, close to 'shatter', throws things out in every direction so they land with no pattern, but each thing survives. Fog dissipates off the hills until nothing is left; a break shot scatters the balls, which all still lie on the table. One vanishes; the other merely spreads.
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.
scatter
To scatter is to send things flying apart so they land here and there with no order — a handful of gravel flung across a path, papers blown off a desk, a flock startled into the air. The word stresses suddenness and irregularity: what scatters is strewn unevenly and left wherever it falls, not neatly distributed. It works both ways, much like its cousin disperse — a crowd can scatter, or police can scatter it — but where disperse suggests an even thinning-away, scatter keeps that sense of a sudden, random fling.

Ask whether the things vanish or just spread. Dissipate thins a thing out until nothing remains — a fog lifting off the hills into clean air. Scatter flings things apart with no pattern, but they all still exist — balls flung across a table. If something spreads out and fades to nothing, that is dissipate; if things are thrown apart but remain, that is scatter.

The tell is what is left: scatter spreads things out but they still exist somewhere, while what dissipates loses itself completely and is gone. Dissipate is gradual and usually of formless things (fog, heat, mood); scatter is sudden and usually of countable things (balls, seeds, people). One vanishes; the other survives, spread wide.
A close pair worth separating in exam writing. Scatter is for countable things flung apart but still there — 'scattered papers', 'scattered showers'. Dissipate is for something formless thinning to nothing — 'the heat dissipated', 'the crowd's anger dissipated'. Examiners reward the tell: scatter spreads things that remain, dissipate fades a thing to nothing. The nouns are dissipation and scattering.
