Question
How is a gas defined?
- Indefinite shape, indefinite volume
- Definite shape, definite volume
- Found in stars
- Definite volume, indefinite shape
Hint:
Gases fill up all empty spaces.
The correct answer is: Indefinite shape, indefinite volume
- Gas fills up any empty space.
- In gases intermolecular forces of attraction are negligible.
- In gases, intermolecular space is very large.
- Gases have no definite shape or volume.
