Slide 11 - Tekstslide

Measurement of Time

Slide 12 - Tekstslide

Measurement of Temperature

Slide 13 - Tekstslide

Measurement of Mass

Slide 14 - Tekstslide

Measurement of Liquid Volume
  • Measuring cylinder - used when high accuracy is not an essential factor.

Slide 15 - Tekstslide

Measurement of Liquid Volume
  • Volumetric pipettes - the most accurate way of measuring a fixed volume of liquid, usually 10 cm3 or 25 cm3

Slide 16 - Tekstslide

Measurement of Liquid Volume
  • Burettes - the most accurate way of measuring a variable volume of liquid between 0 cm3 and 50 cm3 (e.g. in a titration)

Slide 17 - Tekstslide

Measurement of Gaseous Volume
  • Gas syringe - usually the apparatus used to measure the volume of gas

Slide 18 - Tekstslide

Measurement of Gaseous Volume
  • Inverted cylinder - in water may also be used, provided the gas isn't water-soluble

Slide 19 - Tekstslide

Pros and Cons of Measuring Apparatus

Self-Assessment for Learning
Reflection 02
T O    D O:
  • Identify two ideas you do not understand quite well in our sessions.
  • Ask someone who can explain and write the explanations in your notebook.
  • Verify your learning from a classmate by sharing it with the teacher.

Slide 23 - Tekstslide

T O   D O:
  • Using the given chart on the first, second, third, and fourth ionisation energies of elements, construct a bar graph.
  • The x-axis is the element in symbol with atomic number, and the y-axis is the first ionisation energy, in kJ mol -.
  • Share your graphs with the class.

Slide 24 - Tekstslide

  • Ionisation energies show periodicity.
Across a period 
- nuclear charge increases
- atomic radius decreases
- shielding remains constant
- gets harder to remove an electron
- ionisation energy increases
Conclusions from the graphs
