Compare the volume of air and the temperature in Diagram
6.1 and Diagram 6.2.
Temperature
increases , volume of air increases for both diagrams

Based on your observations of
Diagram 6.1 and Diagram 6.2, state the relationship between the two physics
quantities.
When the
temperature of air increases the volume increases/ volume of air is directly
proportional to temperature

By using the Kinetic Theory explain the law mentioned in
b(ii).
When the
temperature increases , distance between the air molecules increases.
Therefore the volume increases
