Boiling or condensing. Formula: (Energy = mass Specific Latent Heat). Gas Pressure and Temperature
Measuring the density of regular and irregular solids (using displacement cans). [KS] KS4 SP14.rar
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. Boiling or condensing
Doing work on a gas (e.g., compressing it quickly) increases its internal energy and can cause a temperature rise. Typical Assessment Objectives Particles are far apart and move randomly at high speeds
Applying the density and latent heat formulas correctly.
