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?
b. Above a certain maximum pressure p2, no boiling transition is observed. What is this pressure?

What minimum external pressure p1 must be applied to the solid if a melting phase transition is to be observed?

p1 = ? Pa

Part B

Above a certain maximum pressure p2, no boiling transition is observed. What is this pressure?

p2 = ? Pa

Explanation:

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
