Tiny particles in constant motion
Closely packed, regular pattern, vibrate in fixed positions
Fixed shape and fixed volume
Close together, random arrangement, move around each other
Take container shape, fixed volume
Far apart, move freely in all directions
No fixed shape/volume, expand to fill container
Assumes solid spheres; reality: varied shapes & structures
Doesn't show forces (e.g. van der Waals, ionic bonds)
Doesn't distinguish atoms, ions & molecules
Assumes same size; reality: particles vary (e.g. He vs protein)
It's a simplified model, doesn't capture all complexities
