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

Measuring the density of regular and irregular solids (using displacement cans). [KS] KS4 SP14.rar

Explaining macroscopic observations (like pressure) using microscopic particle behavior. Energy is used to break intermolecular bonds rather

Faster-moving particles collide with the walls of a container more frequently and with more force, increasing the . [KS] KS4 SP14.rar

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

Doing work on a gas (e.g., compressing it quickly) increases its internal energy and can cause a temperature rise. Typical Assessment Objectives
