Cooled → It is formed from "cool" (from Old English "ceald", meaning not warm) and the suffix "-ed" (indicating a past action or state). The word "cooled" means to have become less warm or to have been made cool.
Think of something that has become 'not warm' ('cool') — the '-ed' shows that this change has already happened.
