Describing something that has two distinct stages or forms.
The diphase process in the experiment showed different results at each stage.
Diphase is formed from "di-" (meaning two) and "phase" (from Greek "phasis", meaning appearance or stage). The word refers to something that has two distinct phases or stages.
Think of 'two' ('di-') different 'stages' ('phase') to remember that diphase means having two phases.
