The coefficient of thermal expansion is
The coefficient of compressibility is
Generally the ideal gas is mathematically represented as
=>
differentiating both side with respect to T at constant P
substituting the equation above into
Recall from ideal gas equation
So
Now differentiate equation (1) above with respect to P at constant T
substituting the above equation into equation of
