- Matter is made up of small particles
- Properties of different states of matter
- Latent heat of vapourisation
PROPERTIES OF DIFFERENT STATES OF MATTER
Solid state:
Solid
Fixed shape
Fixed volume
Solids are rigid, and have negligible compressibility:
Reason:
CHANGE IN STATE OF MATTER
Matter can be change from one state to another by:
Effect of Change of Temperature:
LATENT HEAT
Phase changes are indicated by flat regions where heat energy used to overcome attractive forces between molecules
