Grease traps operate on the principle that grease is ___ than water.

Explanation:
Grease traps rely on the fact that fats and oils have a lower density than water, so they float. As wastewater flows into the trap, the heavier water runs out below while the lighter grease rises to the surface and is held there for removal. Since grease is lighter than water, it forms a distinct layer on top, which is why the correct concept is that grease is lighter than water. (Water is about 1.0 g/cm³, while fats/oils are typically around 0.9 g/cm³ or less, so they don’t mix but separate.)
