Figure 1 shows a single gas particle P of an ideal gas inside a hollow cube.
Figure 1
The cube has side length l and volume V.
P has mass m and is travelling at a velocity c perpendicular to side W.
0 1.2 Explain why P has a change in momentum of −2mc during one collision with W.

0 2Figure 2 shows a wheel used in motorsport. A rubber tyre is fitted around a box
cylindrical metal rim. The tyre is filled with a gas.
The dimensions shown in Figure 2 are for the volume of the gas in the tyre.
Assume that this volume remains constant throughout this question.
Figure 2
0 2 . 1 The mass of the wheel is measured when the gas in the tyre is at a pressure of
1.01 × 105 Pa.
More of the same gas is added to the tyre and the mass of the wheel is
measured again.
Table 1 shows the pressure in the tyre and the mass of the wheel before and after the
addition of the extra gas.
The gas is kept at a constant temperature of 100 °C.
