questions 17 - 25: identify each particle diagram as solid (s), liquid (l) or gas (g).

Explanation:

Step1: Recall particle - arrangement in states

In solids, particles are closely packed in an orderly pattern. In liquids, particles are close together but more randomly arranged and can move past each other. In gases, particles are far apart and move freely.

Step2: Analyze Question 17

The particles are closely packed in an orderly array, so it is a solid (S).

Step3: Analyze Question 18

The particles are far apart, so it is a gas (G).

Step4: Analyze Question 19

The particles are closely - packed but in a more random arrangement than a solid, so it is a liquid (L).

Step5: Analyze Question 20

The particles are in the bottom part of the container, more closely packed than a gas, and can flow to take the shape of the bottom part, so it is a liquid (L).

Step6: Analyze Question 21

The particles are moving freely and are far apart, so it is a gas (G).

Step7: Analyze Question 22

The particles are closely packed in a small area at the bottom, indicating a solid (S).

Step8: Analyze Question 23

The particles are far apart and moving freely, so it is a gas (G).

Step9: Analyze Question 24

The particles are closely packed in an orderly pattern at the bottom, so it is a solid (S).

Step10: Analyze Question 25

The particles are closely - packed but somewhat randomly arranged, so it is a liquid (L).
