✅ Freeze means to turn to ice, but it can also mean to be extremely cold, to feel as if part of you has turned to ice through fear or shock, or to go completely still (The water will freeze at these temperatures; A strange noise in the dark made him freeze in place). ✅ Chill means to become or make something become cold, but it can also informally mean to relax (I chilled the pie before serving; We decided to chill after work). ✅ Chilling something means to make something cold, whereas freezing means to bring it to the temperature at which liquids turn solid. Freeze suggests a greater cold than chill.
