This is the amount of energy required to change the state of 1kg of a substance with no change in temperature. Melting or freezing.

The module focuses on the structure of matter and how particles behave under different conditions. ) is defined as mass per unit volume. Formula:

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) [KS] KS4 SP14.rar

It is the sum of the (related to temperature) and the potential energy (related to state/distance between particles). Specific Latent Heat

Faster-moving particles collide with the walls of a container more frequently and with more force, increasing the . This is the amount of energy required to

Increasing the temperature of a gas increases the kinetic energy of its particles.

Particles are close together but can move past each other in an irregular arrangement. ) is defined as mass per unit volume

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.
