The diagram on the far left shows the moving particles of a gaseous material within a rigid container. Which of the three boxes on the right best represents this material upon the addition of heat?
A)box A because it shows the gas particles rising upon the addition of heat
B)box B because it shows the gas particles moving faster
C)box C because it shows how the particles expand upon the addition of heat
D)All three of these boxes show accurate representations of what happens to the particles within this rigid container upon the addition of heat.

Box B best represents the material upon the addition of heat, as it shows the gas particles moving faster. This is a characteristic of heated gases - as the temperature rises, the particles will move more quickly and with greater energy. Boxes A and C do not accurately represent this behavior, as they emphasize other aspects of gas behavior (rising due to convection in A, and expanding to fill a larger volume in C).
