Revise: Density of MaterialsDensity describes how much mass there is in each unit of volume. Comparing equal volumes makes this clearer: a bag full of metal has much more mass than a similar-sized bag full of feathers.
Paper 5, Paper 6
The space occupied by an object or substance, measured in cubic metres.
Revise: States of matter and densityIn a solid, particles are closely packed and vibrate about fixed positions. They cannot move freely past one another, so a solid keeps a definite shape and volume.
Explain density using particle spacing and mass in a given volume, not just whether the arrangement is regular or random.
For a liquid, subtract the empty container’s mass from the combined mass. Use the measured volume, not the volume you intended to pour.
For density in kg/m³, use mass in kg and volume in m³. Divide grams by 1000 and cubic centimetres by 1 000 000.
