Particle Model
Matter is modelled as particles whose spacing and motion vary with state and temperature.
What to remember
- Gas particles are far apart compared with solids.
- Diffusion results from particle motion.
- Heating increases average particle kinetic energy.
- State changes involve energy transfer.
- Particles are conserved during physical change.
