In an adiabatic change, the pressure and temperature of a monoatomic gas are related with relation as P , where C is equal to
For adiabatic process,
= constant----------------(i)
We have ideal gas relation, PV = RT
-----------------(ii)
From Eqs. (i) and (ii), we get
-------------(iii)
where is adiabatic constant of the gas.
Given,
On comparing with Eq. (iii), we have,
For a monoatomic gas
