Solid water (ice) is slowly warmed from a very low temperature. part a what minimum external pressure p1 must be applied to the solid if a melting phase transition is to be observed?

Explanation:

When the ice melts but there is no change in the temperature.  The only phase change will occur in this case.

The heat energy is spent in changing the phase. The ice will get convert into water. On increasing the pressure, melting point increases.

When the solid water (ice) is slowly warmed from a low temperature.  The minimum external pressure must be 610 Pa which is applied to the solid if a melting phase transition is to be observed.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
