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:

Step1: Recall properties of solid state

In a solid, atoms are closely - packed and arranged in an orderly pattern.

Step2: Draw for solid Xe

Draw a box filled with closely - packed, regularly - arranged circles to represent Xe atoms in the solid state.

Step3: Recall properties of gaseous state

In a gas, atoms are far apart and move randomly.

Step4: Draw for gaseous Xe

Draw a box with a few scattered circles representing Xe atoms, with large spaces between them to show the random and spread - out nature of gas particles.

Answer:

For (i): Draw closely - packed, regularly arranged circles in the box of Diagram 1 to represent solid Xe.
For (ii): Draw a few scattered circles with large spaces between them in the box of Diagram 2 to represent gaseous Xe.
