Measurement of Liquid Volume
Measuring cylinder - used when high accuracy is not an essential factor.
Slide 15 - Slide
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 - Slide
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 - Slide
Measurement of Gaseous Volume
Gas syringe - usually the apparatus used to measure the volume of gas
Slide 18 - Slide
Measurement of Gaseous Volume
Inverted cylinder - in water may also be used, provided the gas isn't water-soluble

Slide 23 - Slide
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.
