Which one of the following statements is not true?a)The molecules in ...
The Incorrect Statement Explained
The correct answer is option 'C': "The molecules in a liquid are arranged in a regular pattern." This statement is not true. Here’s why:
Molecular Arrangement in Liquids
- Liquids do not have a fixed structure.
- Molecules in a liquid are in close proximity but are not arranged in a regular pattern like in solids.
- They have the ability to move past one another, allowing liquids to flow and take the shape of their container.
Comparison with Solids
- In solids, molecules are tightly packed in a fixed, orderly arrangement.
- This regular pattern gives solids a definite shape and volume.
Key Characteristics of States of Matter
- Gases: Molecules exert negligible forces on each other and occupy all available space.
- Liquids: Molecules are close together but can move freely, resulting in no fixed pattern.
- Solids: Molecules vibrate around fixed positions in a structured arrangement.
Conclusion
Understanding the arrangement of molecules in different states of matter is crucial in grasping their physical properties. The erroneous statement about liquids implies a misunderstanding of molecular behavior, which is characterized by random arrangement rather than a regular pattern.
