Liquids Characteristics: Defining Properties
A characteristic of liquids is their distinct behavior regarding shape and volume, differentiating them from solids and gases.
Liquids: Fixed Volume, Variable Shape
Key properties include:
- Fixed Volume: The amount of space a liquid occupies (its volume) remains constant.
- No Fixed Shape: Liquids do not retain their own shape; instead, they conform to the shape of their container.
Evaluating Options for Liquids
Let's analyze the options based on these defining properties:
- Option 1: Describes gases (variable shape, variable volume).
- Option 2: Incorrect; solids have fixed shape, and liquids do not.
- Option 3: Correctly identifies liquids (no fixed shape, fixed volume).
- Option 4: Describes solids (fixed shape, fixed volume).
Therefore, liquids are characterized by having no fixed shape but a fixed volume.
