Long Answer

Isotherms of carbon dioxide at various temperatures are represented in figure. Answer the following questions based on this figure.

(i) In which state will \[\ce{CO2}\] exist between the points a and b at temperature T1?

(ii) At what point will \[\ce{CO2}\] start liquefying when temperature is T1?

(iii) At what point will \[\ce{CO2}\] be completely liquefied when temperature is T2.

(iv) Will condensation take place when the temperature is T3.

(v) What portion of the isotherm at T1 represent liquid and gaseous \[\ce{CO2}\] at equilibrium?

Solution

(i) At T1 (between points ‘a’ and ‘b’) \[\ce{CO2}\] exists in gaseous state.

(ii) At point b, \[\ce{CO2}\] starts liquefying at T1

(iii) At temperature T2, at point ‘g’ \[\ce{CO2}\] will be completely liquefied.

(iv) No condensation at T3 since T3 > Tc.

(v) At T1 liquid and gaseous \[\ce{CO2}\] are at equilibrium between b and c.

  Is there an error in this question or solution?
