Let’s go through each question one by one, step by step.

Question 1: Particles of all matter are in constant random motion.

This is a key idea in the particle theory of matter. Even in solids, particles vibrate. In liquids and gases, they move more freely. So yes — all particles are always moving randomly, even if it’s just vibrating in place.

✔ Correct answer: A True

Question 2: What causes Brownian motion?

Brownian motion is the zigzag movement of tiny particles (like smoke) seen under a microscope. It happens because invisible air molecules are constantly hitting them from all sides. The hits aren’t equal, so the particle jiggles around.

So, it’s not sublimation or diffusion causing it directly — it’s the collisions with air molecules.

✔ Correct answer: A molecules in the air hitting the smoke particles

Question 3: Which statements describe the arrangement of particles in solids?

In solids:
- Particles are packed tightly in an orderly pattern (like soldiers in rows).
- They don’t slide or flow — they’re stuck in place.
- But they DO vibrate back and forth in their fixed positions.

So both A and C are correct? Wait — let’s check the options again.

The question says “which statements” — plural — but the format shows single letters (A, B, C, D). Looking at the image, it seems like only ONE choice can be selected per question (standard multiple-choice).

But wait — option A says “Particles are arranged in an orderly manner” → TRUE for solids.

Option C says “particles vibrate about their positions” → ALSO TRUE.

Hmm… this might be a trick. Let me re-read the question: “Which statements describe...” — but the answer choices are labeled A, B, C, D as separate options. That suggests we pick the BEST or MOST COMPLETE answer — or maybe it's designed to have only one correct letter.

Actually, looking closely at how Quizizz works — usually you select ONE answer per question unless specified otherwise.

But here’s the thing: Option A describes ARRANGEMENT (orderly), which is true.

Option C describes MOTION (vibrating), which is also true.

Wait — perhaps the question is asking specifically about “arrangement”, not motion?

Let’s read carefully: “Which statements describe the arrangement of particles in solids?”

Ah! Key word: arrangement — that refers to how they’re positioned, not how they move.

So “orderly manner” = arrangement → A is correct.

“Vibrate about their positions” = motion → not arrangement.

So even though C is true about solids, it doesn’t describe *arrangement* — it describes *motion*.

Therefore, best answer is A.

B and D are wrong — those describe liquids or gases.

✔ Final decision: A Particles are arranged in an orderly manner

*(Note: If the test allowed multiple selections, A and C would both be right — but based on standard format, we pick A since the question specifies “arrangement”)*

Question 4: Which statement about liquids is correct?

Liquids:
- Take the shape of their container → no fixed shape.
- But they keep the same volume → fixed volume.

Example: Pour water from a cup into a bowl — it changes shape, but still has same amount (volume).

So:

A: “no fixed shape but fixed volume” → ✔ CORRECT

B: fixed shape? No → ✘

C: no fixed shape AND no fixed volume? That’s gas →

D: fixed shape and volume? That’s solid → ✘

✔ Correct answer: A They have no fixed shape but they do have a fixed volume.

Question 5: The particles of solids _______________

We already know:
- Solids: particles are locked in place, vibrating.
- Don’t move freely → not B
- Can’t slide over each other → not C (that’s liquid)
- Do move — they vibrate → so “do not move” is false → not A

Only D makes sense: “vibrate about their fixed positions”

(Note: typo in option D — “postions” should be “positions”, but we ignore typos.)

✔ Correct answer: D vibrate about their fixed postions

---

Question 6: The particles of liquids _______________

Liquids:
- Particles can slide past each other → allows flowing.
- Not fixed in place → so not vibrating in fixed positions (that’s solid).

Option A: “are able to slide over each other” → ✔ YES — that’s why liquids flow.

Option B: “vibrate about their fixed positions” → that’s solids → ✘

✔ Correct answer: A are able to slide over each other
