Why does soap clean dishes?
Show answer & explanation
Answer: Molecules grab water and oil
Molecules grab water and oil ✓ — Correct! Soap molecules are special: one end likes water, the other likes oil and grease. When you wash dishes, soap surrounds grease with its oil-loving ends, while water-loving ends face outward. This lets water rinse away the grease. It's like a molecular bridge between oil and water!
It kills all bacteria — Wrong. While some soaps have antibacterial properties, that's not how they clean dishes. The primary cleaning action comes from the molecular structure that allows soap to bind both water and oils, lifting away grease.
It dissolves grease directly — Wrong. Soap doesn't dissolve grease chemically. Instead, soap molecules physically surround grease droplets and suspend them in water. The grease is lifted and washed away, not dissolved or broken down.
