Problem 49E

Solid water (ice) is slowly warmed from a very low temperature. (a) What minimum external pressure p1 must be applied to the solid if a melting phase transition is to be observed? Describe the sequence of phase transitions that occur if the applied pressure p is such that p < p1. (b) Above a certain maximum pressure p2, no boiling transition is observed. What is this pressure? Describe the sequence of phase transitions that occur if p1 < p < p2.

ANSWER:

Solution 49E

Problem (a)

Step 1:

In Case of Solid water (Ice) the minimum pressure(P1) to have melting phase transition is greater than triple point pressure. For water it is 610 Pa.
