A student investigates how the volume of a gas changes as its pressure is varied at a constant temperature. Their results are plotted on the graph in Figure 1.

Figure 1: Line graph showing how the volume of a gas changes with pressure. The horizontal x-axis is labelled 'Pressure (kPa)' and has grid marks from 0 to 300 with intervals of 50. The vertical y-axis is labelled 'Volume (cm³)' and has grid marks from 0 to 120 with intervals of 20. A smooth curve slopes downwards from left to right, passing exactly through the coordinates (80, 100), (100, 80), (160, 50), and (200, 40).

Use the graph in Figure 1 to estimate the volume of the gas at a pressure of 160 kPa.
