Which of the following properties is not characteristic of liquids?

Mr. S M HUSSAIN · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
 **Primary Concept**: Properties of matter
 **Related Topics**: States of matter, intermolecular forces
 **Prerequisites**: Understanding the characteristics of solids, liquids, and gases.
## SOLUTION PATHWAY
**Given Information**:
  The question asks to identify a property NOT characteristic of liquids.
  Options: Definite shape, definite volume, fluidity, surface tension.
**Method & Steps**:
 1. Analyze each option to determine if it applies to liquids.
  Reasoning: Liquids are characterized by their ability to flow and take the shape of their container, while maintaining a relatively constant volume.
 2. Identify the option that does not fit the description of a liquid.
  Working: 
        * Definite shape: Liquids do not have a definite shape; they adapt to the shape of their container.
        * Definite volume: Liquids have a definite volume, meaning they occupy a specific amount of space.
        * Fluidity: Liquids are fluid, meaning they can flow and change shape easily.
        * Surface tension: Liquids exhibit surface tension due to the cohesive forces between their molecules.
 3. Conclude which property is not characteristic of liquids.
  Result:  A definite shape is not a characteristic of liquids.
  Verification: The other options (definite volume, fluidity, surface tension) are all properties of liquids.
 ## OPTION ANALYSIS
A ✓: Definite shape: Liquids do not have a definite shape; they conform to the shape of their container. This is the correct answer.
B :x: Definite volume: Liquids maintain a constant volume regardless of the container's shape.
C :x: Fluidity: This is a defining characteristic of liquids; their ability to flow.
D :x: Surface tension: This is a property arising from the cohesive forces within a liquid.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing liquids with solids: Solids have a definite shape and volume, unlike liquids.
  2.Overlooking the concept of fluidity:  Fluidity is a key distinction between liquids and solids.
 **Quick Tips**:
  1.Think about how liquids behave in different containers to understand their shape.
  2.Remember that liquids are fluid and have a definite volume, but not a definite shape.
