What do you mean by postulates of kinetic theory of gases?

The postulates of Kinetic Theory was developed in the nineteenth century explaining the behaviour of gases. Kinetic Theory gives:

i) molecular interpretation of pressure and temperature of a gas, and is consistent with gas laws and Avogadro's hypothesis.

ii) explains specific heat capacities of many gases.

iii) relates measurable properties of gases such as viscosity, conduction and disffusion with molecular parameters.
