Part C Check your graph prediction. In Frame 4, click the view icon and select Plot View. You may click on any graph point to see the t and x values
displayed. (Clicking a graph point also jumps the video to the frame for that data and highlights data for that point in any data tables.) How does
the graph compare with your prediction?

Sublimation- which change of state is shown in model

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
