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.

Applying the density and latent heat formulas correctly. [KS] KS4 SP14.rar

This is the amount of energy required to change the state of 1kg of a substance with no change in temperature. Melting or freezing. Particles are far apart and move randomly at high speeds

Energy is used to break intermolecular bonds rather than increasing temperature during melting or boiling. The total energy stored by particles in a system. followed by liquids

Explaining macroscopic observations (like pressure) using microscopic particle behavior.

Solids are generally the most dense, followed by liquids, then gases.
