Particles are close together but can move past each other in an irregular arrangement.
Increasing the temperature of a gas increases the kinetic energy of its particles.
Doing work on a gas (e.g., compressing it quickly) increases its internal energy and can cause a temperature rise. Typical Assessment Objectives [KS] KS4 SP14.rar
Applying the density and latent heat formulas correctly.
Explaining macroscopic observations (like pressure) using microscopic particle behavior. Particles are close together but can move past

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) Core Concepts of KS4 SP14 (Particle Model) Energy
Energy is used to break intermolecular bonds rather than increasing temperature during melting or boiling. The total energy stored by particles in a system.
