Liquids' shape and molecular arrangement

Steps:

• Recall that liquids flow and adapt to the container's bottom and sides, lacking a fixed shape.
• Note that liquid molecules are close together but move freely, forming an irregular, disordered arrangement.
• Match these properties to the options: shape description and arrangement type.
• Select the option that aligns with both traits without contradictions.

Why C is correct:

• Liquids take the shape of their container due to gravity and fluidity, and their molecules have a not regular (disordered) arrangement, as defined in states of matter.

Why the others are wrong:

• A: Fixed shape applies to solids, not liquids.
• B: "Takes fixed container" is unclear and incorrect; liquids adapt to the container, not fix it.
• D: Regular arrangement describes crystalline solids, not liquids.

Final answer: C
