Question
Which of the following statements about the P_T phase diagram shown here is true? The slope of the liquid-vapor coexistence line is consistent with the vapor pressure of a liquid increasing with temperature. The relative position of the vapor and liquid phases is consistent with the vapor phase being less dense than the liquid phase. The succession of phases shown as T increases at constant P just below the triple point pressure is consistent with what is observed for water. The succession of phases shown as P increases at constant T at a temperature just below the triple point is not consistent with what is observed for water. B and C. B and D A and C A and DExplanation / Answer
A. The slope of the liquid-vapor co-existence line is consistent with the vapor pressure of a liquid increasing with temperature. - It is well known that vapor pressure increase with temperature which is exactly what is indicated in the phase diagram.
D. The succession of phases shown as P increases at constant T at a temperature just below the triple point is not consistent with what is observed for water. - In case of water, increase in P at constant temperature just below the triple point changes the phase from water vapor to ice i.e vapor to solid where as in this case it shows that as P increases at constant Temperature, phase changes from solid to liquid. So this statement is true.
A and D are true.
