1 a) Drawing Bar Graphs

Ensure axes are labelled with units, suitable size and scale. Bars labelled and at correct levels.

1 b) Drawing Line Graphs

Ensure axes are labelled with units, suitable size and scales. Plot points accurately and line of best fit drawn.

1 c) Interpreting Graphs

1) As the temperature increases the solubility of sulphur dioxide decreases

2) volume= 20cm3(approx use graph)

3) time=30s(approx- use graph)

4) as the temperature increases to 370Cthe units of sugar produced increases and then decreases as the temperature continues to increase.

5) volume= 15cm3 (approx use graph)
