PART C
1. When a balloon is inflated at constant temperature, both the volume and the pressure will increase. Explain why Boyle's law is not applicable in this example.
2. Draw a graph to indicate how the graph obtained in PART B No. 8 will behave at very high pressure.
3. Consider the following graphs of pressure versus the reciprocal of volume for a given mass of a particular gas.
P (kPa)

$$T_1$$
$$T_2$$
$$T_3$$
$$\frac{1}{V}$$ ($$cm^{-3}$$)
