Question

for parts of the free - response question that require calculations, clearly show the method used and the steps involved in arriving at your answers. you must show your work to receive credit for your answer. examples and equations may be included in your answers where appropriate. answer the following questions related to xe. (a) diagram 2 shown above represents a particle - level view of liquid xe atoms. (i) in the box in diagram 1, draw a particle - level view that represents a vessel that contains only solid xe. note on your ap exam, you will handwrite your responses to free - response questions in a test booklet (ii) in the box in diagram 2, draw a particle - level view that represents a vessel containing only gaseous xe.

Explanation:

In a solid, atoms are closely - packed in an orderly arrangement. For gaseous Xe, atoms are far apart and move randomly.
For the solid Xe drawing: Draw the Xe atoms closely packed together in a regular, repeating pattern (like a lattice).
For the gaseous Xe drawing: Draw the Xe atoms scattered throughout the container with large spaces between them and no particular order.

Answer:

(i) Draw Xe atoms in a closely - packed, regular pattern in diagram 1 box to represent solid Xe.
(ii) Draw Xe atoms scattered with large spaces between them in diagram 2 box to represent gaseous Xe.
