X'inhu t-trab?

Dak li nsejħu "trab" huwa biss ġabra ta 'partiċelli fini u solidi ta' materjal partikolari - kemm jekk huwa trab tal-ħamrija f'għalqa, serratura minn xogħol tal-injam, jew it-trab tad-dar li jinġabar fi djarna. Il-partiċelli li jiffurmaw it-trab huma ta' ħafna daqsijiet differenti - għalkemm dawn kollha huma żgħar u ħfief biżżejjed biex jinġarru fl-arja.
