Identify true and false statements for fixed amount of gas in following isotherm of real gas.
(i) Keeping pressure constant state `x` can be converted into state `y` only by decreasing volume.
(ii) Keeping volume constant state `x` can be converted into state `z` only by decreasing pressure.
(iii) State `x` can never be converted into state `z` only by increasing pressure at the temperature above `C`.
(iv) Below temperature `C` state `x` cann't exist at any pressure.
(v) State `x,y` and `z` gas, liquid and liquid vapour respectively.
(vi) State `x` canbe converted into state `y` at temperature `d` and pressure `F`.

Answer

(i) T, (ii) T, (iii) T, (iv) F, (v) T, (vi) T
