  1. The Properties of Matter

  2. Characteristic vs. Non characteristic properties • A characteristic property is something that is specific to that substance. (i.e. Density, melting point, boiling point) • Non-characteristic properties are common to many substances. (i.e. states of matter, temperature, volume, mass, acidity and alkalinity)

  3. Terminology • States of matter : (solid, liquid or gas) • Mass : the quantity of matter of the substance • Volume: the space that matter occupies • Temperature: quantity of heat an object or matter contains • Acidity and alkalinity : determines whether a substance is an acid, a base or neutral in its chemical composition.

  4. States of Matter • Solids: • - Particles held tightly together by chemical bonds • - Particles cannot move freely. Only vibrate

  5. States of Matter • Liquids: • - Particles held weakly together (compared to solids) • - Particles can move slightly with respect to each other.

  6. States of Matter • Gases: • - Particles are far apart from each other. • - Particles move freely

  7. Particle Theory • Matter is composed of particles that are invisible to the naked eye.

  8. UNITS • Metre : (m)  Length • Kilogram : (kg)  mass • Gram : (g)  mass • Second: (s)  time • Litre (L)  volume • Millilitre (ml)  volume • Cubic centimetre cm3

  9. Mass vs. Weight • Mass stays the same...weight changes

  10. Temperature Vs. Heat • Heat : form of energy • Temperature : indication of the amount of energy

  11. Temperature and atmospheric pressure • Pressure :A force exerted on a surface • Temperature varies with atmospheric pressure • - Greater Atm pressure  greater temperature needed to change state

  12. Temperature and particle theory • Increase temperature  increase speed of particles
