CSEC Physics · May/June 2007 · Paper 2 · Question 1(b)

Plot a graph of volume, V, (y-axis) against temperature, T, (x-axis). The axes have been drawn for you. The scale for the x-axis should include the range -300°C to +300°C, with 50 °C per division. Label the graph line of V against T "Line 1".

This question uses a figure or table from the paper — you'll see it when you practise.
