Particles are close together but can move past each other in an irregular arrangement.
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. [KS] KS4 SP14.rar
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 close together but can move past
Applying the density and latent heat formulas correctly. Mass is conserved during a change of state
Doing work on a gas (e.g., compressing it quickly) increases its internal energy and can cause a temperature rise. Typical Assessment Objectives
It is the sum of the (related to temperature) and the potential energy (related to state/distance between particles). Specific Latent Heat
Particles are in a fixed, regular arrangement and vibrate around fixed positions.
