- States of Matter
- Arrangement of Atoms/ Molecules in Solids, Liquids and Gases: - (Intermolecular Space, Cohesive Forces)
- Characteristics of Molecules of Matter
- Change of State of Matter
States of Matter
Classification of matter into solid, liquid and gas on the basis of properties (shape, volume). Factors responsible for the existence of matter in different states.
Arrangement of atoms/ molecules in solids, liquids and gases: - intermolecular space, cohesive forces).
There is space between the particles of matter.
