For a certain range of pressures, it is suggested that the relation between the pressure P and volume V of one mole of the gas at constant temperature is given by the equation PV = A + BP where A and B are constants. In an experiment to measure the deviation of nitrogen gas from ideal gas behaviour, 1 mole of nitrogen gas was compressed at a constant temperature of 150 K. The volume V of the gas was measured for different values of the pressure P . A graph of the product PV of pressure and volume was plotted against the pressure P and is shown below. (Error bars showing the uncertainties in measurements are not shown). (a) Draw a line of best fit for the data points. (1) (b) Use the graph to determine the values of the constants A and B in the equation PV = A + BP.

(5) (c) State the value of the constant B for an ideal gas. ..................................................................................................................................... (1) (d) The equation PV = A + BP is valid for pressures up to 6.0 × 10 7 Pa.
