Physics & Chemistry - Topics for February 2015 Exam

Physics and Chemistry – 2° Year - Syllabus – 2014

States of matter

• Show how the particle theory of matter can be used to explain the properties of solids, liquids and gases, including changes of state.

• Changes of state: Melting/Fusion, Freezing/solidification, Evaporation, Boiling, Condensing, Sublimation. Graphs.Heating and cooling curves

Gases & Pressure

Variables affecting the gaseous state of matter. Definition of Pressure. Volume, temperature and n° of particles.

Material properties

• Distinguish between elements, compounds and mixtures. Difference between atom and molecule

• The link between elements and atoms. Simple atom model: protons, electrons and neutrons

• Mass number and atomic number

• Give chemical symbols for the first twenty elements of the Periodic Table.

• Mixtures. Understand that mixtures can be separated. Different types of mixtures: suspension, solution, emulsion.

• Solutions: solute & solvent. Saturated, unsaturated, and supersaturated. Temperature. Solubility  

• Describe and explain the differences between metals and nonmetals. Alloys.

• Compounds. Name common compounds including oxides, hydroxides, chlorides, sulfates and carbonates. Understand that they are formed by chemical reactions.

Material changes

• Difference between physical and chemical change

• Describe everyday chemical reactions, e.g. rusting, combustion, respiration, photosynthesis

Electrostatics

• Describe electrostatics and the concept of charge. Relate it to the atom.

•Difference between conductors and insulators.
