Sense: verb/1
All four words describe a group or mass ceasing to be in one place, but they differ in register and typical subject. 'Scatter' is the most everyday word and works equally well for small objects (leaves, marbles) and for people; it often suggests a sudden, slightly chaotic motion. 'Disperse' is a step more formal and is the default verb used in news reporting about crowds, protests, and police action: the crowd dispersed; police dispersed the protesters. 'Break up' is informal and phrasal — natural for parties, meetings, and gatherings ending. 'Dissipate' rarely takes people; it typically applies to mist, smoke, heat, or feelings (her anger slowly dissipated). So a journalist writes 'police dispersed the crowd', a friend texts 'the party broke up around midnight', and a novelist writes 'the morning fog dissipated by ten'.

Etymology
From Latin 'dispergere', meaning 'to scatter widely', formed from 'dis-' (apart, in different directions) plus 'spargere' (to scatter or sprinkle). The verb entered English in the late 14th century through Middle French, first used of physically scattering things and people, and later extended to ideas, light, and fine substances spreading outward from a source.
