6. You get to your dive site and park the car. You put on your gear and get ready to enter the water. But first you check your scuba tank. It is filled to a pressure of about 25,000 kPa at 300 K. The volume of the tank is 25 L. You begin to wonder: If pressure remains constant, what would happen to the volume of gas in the tank if its temperature increased? (6 points) a. Which of the four thermal processes describes the temperature-volume relationship at constant pressure? (3 points)

b. Write the equation for this process. Hint: Think about the first law of thermodynamics. (3 points)

You get 6 for mechanical

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.
