[ks] Ks4 Sp14.rar Today

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

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).

If the .rar file you are referring to is a study pack or assessment resource, the following write-up serves as a comprehensive summary of the core concepts generally included in this module. Core Concepts of KS4 SP14 (Particle Model)

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

Particles are close together but can move past each other in an irregular arrangement.
