Particles are in a fixed, regular arrangement and vibrate around fixed positions.
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
Faster-moving particles collide with the walls of a container more frequently and with more force, increasing the . Particles are in a fixed, regular arrangement and
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. Particles are in a fixed
Measuring the density of regular and irregular solids (using displacement cans).
Energy is used to break intermolecular bonds rather than increasing temperature during melting or boiling. The total energy stored by particles in a system.
