Compressibility factor, Z of a gas is given as `Z=(pV)/(nRT)`
(i) What is the value of Z for an ideal gas ?
(ii) For real gas what will be the effect on value of Z above boyle's temperature ?

Text Solution

Verified by Experts

(i) For ideal gas, Z=1.
(ii) For a real gas, above Boyle's temperature, gas shows positive deviation and hence `Z gt 1`
