Isotherms of carbon dioxide at various t...

Isotherms of carbon dioxide at various temperature are represented in Fig.
Answer the following questions bases of this figure.
(i) In which state will `CO_(2)` exist between the pointa a and b a temperature `T_(1)`?
(ii) At what point will `CO_(2)` start liquefying when temperature is `T_(1)`?
(iii) At what point wil `CO_(2)` be completely liquafied whe temperature is `T_(2)`.
(iv) Will condensation take places when the temperature is `T_(3)`.
(v) What portion of the isotherm at `T_(1)` represents liquid and gaseous `CO_(2)` at equilibrium ?

Text Solution

Verified by Experts

(i) gaseous state
(ii) at point b
(iii) at point g
(iv) No, condensation will occur when temperature is `T_(3)` because `T_(3) gt T_(c )`.
(v) between b and c.
