1. 1(a)3 marksComplete Table 1 by calculating the temperature, T / K.
2. 1(b)6 marksUse the readings from the completed Table 1 to plot a graph of length of the air column (L/mm) against Temperature (T/K) on the graph page on page 2. The L-axis starts at 140 mm and the T-axis starts at 270 K.
3. 1(c)4 marksFrom your graph, calculate the slope, S.
4. 1(d)1 markWhat information does the slope (gradient) of the graph provide?
5. 1(e)1 markUse your graph to determine the value of the length of the air column at 273 K.
