Step-by-step solution for: Particle Nature of Matter online exercise for
Here are the answers to the worksheet questions based on the particle nature of matter.
1. What are the three states of matter?
The three common states of matter are:
1. Solid
2. Liquid
3. Gas
2. What is the smallest possible unit of matter called?
An atom. (Note: In some contexts, "particle" or "molecule" might be accepted depending on the specific lesson, but "atom" is the fundamental unit of an element).
3. True or false: when 500 ml of water is mixed with 500 ml of isopropyl alcohol, the result is 970 ml of liquid because some was spilled.
False.
*Reasoning:* The volume decreases not because of spilling, but because the smaller particles of one liquid fit into the spaces between the larger particles of the other liquid. This demonstrates that there is empty space between particles of matter.
4. Particles of matter cannot be seen because they are....
d. tiny
5. Why did the soccer ball deflate in cold temperatures?
When the temperature gets colder, the air particles inside the ball lose energy and move slower. Because they are moving slower, they don't push against the walls of the ball as hard, and they take up less space. This causes the pressure inside to drop and the ball to shrink or deflate.
6. Why do the marshmallows get bigger inside the vacuum chamber when the air is removed?
Marshmallows have tiny pockets of air trapped inside them. When the air is pumped out of the vacuum chamber, the pressure outside the marshmallow becomes very low. The air trapped *inside* the marshmallow still has normal pressure, so it pushes outward against the soft candy structure, causing the marshmallow to expand.
7. True or false: a particle of matter is about the width of a human hair.
False.
*Reasoning:* Particles of matter (atoms) are much, much smaller than a human hair. A human hair is visible to the naked eye, while atoms are microscopic.
8. Fill in the blank:
Matter is anything that has weight (mass) and takes up space.
9. What makes Zoe’s rockets work?
*(Note: This refers to a specific experiment likely done in class, usually involving baking soda and vinegar or Alka-Seltzer tablets).*
The reaction creates carbon dioxide gas. As the gas particles are created, they move rapidly and build up pressure inside the sealed container until the lid pops off, pushing the rocket upward (Newton's Third Law: for every action, there is an equal and opposite reaction).
10. Why was the carbon dioxide in the balloons a solid when the balloons were cut open?
Carbon dioxide turns into a solid (called dry ice) when it is under very high pressure and extremely cold temperatures. Inside the pressurized tank or balloon system, the CO2 is compressed. When released suddenly or exposed to the cold conditions of the experiment, it can freeze directly into a solid.

Final Answer:
1. Solid, Liquid, Gas
2. Atom
3. False
4. d. tiny
5. The air particles moved slower and took up less space due to the cold.
6. The air trapped inside expanded because the outside pressure was removed.
7. False
8. Matter
9. The buildup of gas pressure pushed the rocket up.
10. High pressure and cold temperatures turned the gas into a solid.
