Like a picture, a picture. As can be seen from the figure, the graph line is a straight line passing through the origin, which proves that Boyle's law is correct.

② As can be seen from the figure, when P=8.85× 105Pa, 1V = 5.8m3, then V=0. 172m3.

③ According to mathematical knowledge, the slope of the image is equal to PV, and according to the gas equation PVT = C, PV is directly proportional to T, so the greater the slope, the greater the PV value and the higher the gas temperature.

So the answer is: (1)D(2)① sketch, and the graph line is a straight line passing through the origin, which proves that Boyle's law is correct? ②0. 17 0.0 1m3

③ The greater the slope, the higher the gas temperature.
