two identical pots, one black and one silver, containing exactly the same amounts of water, are heated to the same
temperature. they are left uncovered and placed in the same room. after 15 minutes the water in the black pot is significantly
cooler than the water in the silver pot. which of these statements best explains this difference?

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. 

Ok what do you need with
