AQA GCSE Physics (8463) — Particle model of matter
What You Need to Know
Define density using the equation:
ρ
=
m
V
\rho = \frac{m}{V}
ρ
=
V
m
Use the particle model to explain the different states of matter and differences in density.
Recognise and draw simple diagrams modelling solids, liquids, and gases.
Explain differences in density in terms of atom or molecule arrangement.
Determine the densities of regular and irregular solid objects and liquids using appropriate apparatus and displacement techniques.
