Which statement about liquids is INCORRECT?
- A. Liquids diffuse more slowly than gases
- B. Liquids are almost incompressible
- C. The molecules of a liquid are held in fixed positions
- D. Liquids have a definite volume but no definite shape
Explanation
Molecules in a liquid are in constant random motion and slide freely past one another, which is exactly what allows a liquid to flow and to diffuse, however slowly. Fixed positions belong to the solid state. The other three statements are all correct, and incompressibility follows from the molecules already being nearly in contact.
