Let's go through each question from the worksheet titled
"Bill Nye: Phases of Matter" and provide the correct answers with explanations.
---
1. Everything you can touch is made of
Answer: *Matter*
Explanation: All physical objects that have mass and take up space are made of matter. This includes solids, liquids, and gases.
---
2. Solid, liquid, and gas are the three _____________ of matter.
Answer: *Phases* (or *States*)
Explanation: The three main states or phases of matter are solid, liquid, and gas. These describe how particles are arranged and move in a substance.
---
3. The atoms in a solid move more ____________ than in a liquid.
Answer: *Slowly*
Explanation: In solids, atoms are tightly packed and vibrate in place. They don’t flow like in liquids, so their motion is limited and slower compared to the more free-moving particles in liquids.
---
4. Matter can change phases by changing the amount of ____________.
Answer: *Energy* (specifically heat energy)
Explanation: Adding or removing energy (usually heat) causes changes in phase. For example, adding heat turns ice (solid) into water (liquid), and then into steam (gas).
---
5. Air is 78% ____________.
Answer: *Nitrogen*
Explanation: Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and small amounts of other gases like argon and carbon dioxide.
---
6. Water vapor is an example of a(n) ____________.
Answer: *Gas*
Explanation: Water vapor is water in its gaseous state. It forms when liquid water evaporates into the air.
---
7. Energy does / does not change the phase of matter.
Answer: *does*
Explanation: Energy (especially thermal energy) causes molecules to move faster or slower, which leads to phase changes. For example, heating water turns it into steam.
---
8. Absolute Zero is when energy / molecules stop moving.
Answer: *molecules*
Explanation: Absolute zero (0 Kelvin or -273.15°C) is the theoretical temperature at which all molecular motion stops. At this point, particles have minimal kinetic energy.
---
9. You can use _______________ to change a liquid into a gas.
Answer: *Heat* (or *Energy*)
Explanation: Adding heat increases the kinetic energy of the molecules in a liquid, allowing them to break free and become a gas. This process is called evaporation or boiling.
---
Final Answer Key:
1. Matter
2. Phases (or States)
3. Slowly
4. Energy
5. Nitrogen
6. Gas
7. does
8. molecules
9. Heat (or Energy)
These answers align with basic science concepts taught in Bill Nye’s "Phases of Matter" video and related educational materials.
