Particles are far apart and move randomly at high speeds. Changes of State Physical changes (reversible) rather than chemical changes. Mass is conserved during a change of state.
Measuring the density of regular and irregular solids (using displacement cans). [KS] KS4 SP14.rar
The module focuses on the structure of matter and how particles behave under different conditions. ) is defined as mass per unit volume. Formula: Particles are far apart and move randomly at high speeds
