Course review
Review each learning objective in this topic, then open its concept explanation or question set.
Learning objective
• Elements: primary constituents of matter, cannot be chemically broken down • Compounds: atoms of different elements bonded in fixed ratio • Mixtures: more than one element/compound in no fixed ratio, separated by physical methods • Distinguish homogeneous and heterogeneous mixtures and choose separation methods
Start with the concept explanation, then practise to create mastery evidence.
Learning objective
• Explains physical properties of matter (solids, liquids, gases) and changes of state • State symbols: s, l, g, aq • Name changes of state: melting, freezing, vaporization, condensation, sublimation, deposition
Start with the concept explanation, then practise to create mastery evidence.
Learning objective
• Temperature T (Kelvin) = measure of average kinetic energy Ek • Convert between Celsius and Kelvin scales • Interpret temperature and physical property changes during changes of state
Start with the concept explanation, then practise to create mastery evidence.
