Characterisation of Reversible Adiabatic Process

Let us find out the path followed by the system in reaching the final sate starting from the initial state. We have already seen that for an ideal gas

(8.1)

or,

(8.2)

or,

(8.3)

or,

(8.4)

or

= constant

(8.5)

Since,

(8.6)

From (8.4) and (8.6) we get

(8.7)

or,

(8.8)

or,

=constant
