Draw a graph showing the change in temperature of water over time when heated, using the data from the previous experiment and the given marking scheme.

As an AI, I cannot physically draw the graph on the provided grid. However, I can guide you on how to complete it based on the previous experiment (heating water) and the marking criteria.

• Labelling x-axis and y-axis correctly (1 mark):

  • The horizontal axis (x-axis) should be labelled: Time (minutes)
  • The vertical axis (y-axis) should be labelled: Temperature ($^\circ\text{C}$)

• Correct plotting line graph drawn (1 mark):

  • Plot the data points from the table (from the previous question) with Time on the x-axis and Temperature on the y-axis.
  • Connect the plotted points with a smooth curve or straight lines. The graph should show the temperature increasing steadily, then flattening out into a horizontal line at $100^\circ\text{C}$ once the water starts boiling.

• Correct caption (2 marks):

  • A suitable caption for the graph would be: Graph showing the change in temperature of water over time when heated.
