The compressibility factor of a gas is given by (where, V₁ = actual volume of the gas V₂ = gas volume predicted by ideal gas law )?
Answer: Option 1 The compressibility factor is given by $$Z = \frac{{P{V_1}}}{{RT}}.$$ If at the same temperature and pressure if the same gas exists as ideal gas than we...
