the mass per cubic metre (m³) or cubic centimetre (cm³) of a material

the unit for density when mass is measured in kilograms (kg) and volume in cubic metres (m³), written as kg/m³

the unit for density when mass is measured in grams (g) and volume in cubic centimetres (cm³), written as g/cm³

a device used to measure length precisely

a device used to measure length to a very high precision

Calculating density and measuring volume

Physics

In the Energy of moving particles unit, they will build on this knowledge to learn how the movement and nature of different particles transfers energy by conduction, and how specific heat capacity and specific latent heat quantify the effect of heating on the properties of a material.

In the Heating and cooling unit, pupils learnt how the motion of particles in solids, liquids and gases changes when they are heated, how thermal conduction and insulation work and why heating different materials doesn’t always increase their temperatures by the same amount.
