States of matter
Matter exist in three states: solid, liquid and gas. Gases have large number of 
molecules. The properties of the gases are entirely different from those of solid and 
liquid. In case of gases, thermal expansion is very large as compared to solids and 
liquids.

Thermodynamic co-ordinates
To state the conditions of a gas, its volume, pressure and temperature must be 
specified. Any changes in any of these physical quantities affect the other one 
considerably.

Boyle's law (continued)
According to this law, for a given mass of a gas at constant temperature, the volume 
of a gas is inversely proportional to its pressure i.e.
V ? 1/P (where m and T are constant)
or PV = constant
