Step-by-step solution for: Bill Nye - Phases of Matter Worksheet | Pango
It looks like you've uploaded a worksheet titled "Bill Nye Phases of Matter", which contains 12 questions related to the states of matter, phase changes, and related concepts. However, I can't view or analyze images directly. But based on your description and the visible text in your message, I can help you solve the questions and provide explanations.
Let me go through each question one by one and give you the correct answers with clear explanations:
---
Answer: Matter and energy
Explanation: The universe consists of matter (anything that has mass and takes up space) and energy (the ability to do work or cause change).
---
Answer: Solid, liquid, gas
Explanation: These are the three common states of matter. Solids have a fixed shape and volume, liquids have a fixed volume but take the shape of their container, and gases have neither fixed shape nor volume.
---
Answer: The arrangement of particles (or the state of matter)
Explanation: Molten steel is liquid because its particles move freely and are not locked in place, while solid steel has particles arranged in a fixed structure. The substance is the same—just in different physical states.
---
Answer: Energy (heat) or removal of energy (cooling)
Explanation: To change from solid to liquid (melting), heat energy is added. To change from liquid to gas (evaporation), more heat is added. Conversely, cooling removes energy and causes phase changes like freezing or condensation.
---
Answer: By removing heat from the inside and releasing it outside
Explanation: Refrigerators use a refrigerant that absorbs heat from the interior (causing cooling) and releases it into the surrounding air through the back coils. This process relies on evaporation and condensation of the refrigerant.
---
Answer: Heat energy (or adding energy)
Explanation: Melting a solid into a liquid requires energy to break the bonds holding the particles together.
---
Answer: Nitrogen is a liquid at -196°C. Nitrogen makes up 78% of the air we breathe.
Explanation: Nitrogen boils at -196°C under standard pressure. It's the most abundant gas in Earth’s atmosphere.
---
Answer: It became very brittle and shattered easily (or froze instantly)
Explanation: Liquid nitrogen is extremely cold (-196°C). When an onion is placed in it, it freezes rapidly, making it fragile and prone to breaking apart.
---
Answer: Carbon dioxide
Explanation: Dry ice is solid carbon dioxide (CO₂). It sublimes (turns directly from solid to gas) at room temperature without becoming a liquid.
---
Answer: Lower
Explanation: Temperature is a measure of the average kinetic energy of particles. Slower-moving molecules have less kinetic energy, so the temperature is lower.
---
Answer: Stop (or rest)
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 thermal motion.

*(This likely refers to a diagram or multiple-choice section where students match properties to solids, liquids, and gases.)*
Example:
- Solid: Definite shape and volume → ✔
- Liquid: Definite volume, no definite shape → ✔
- Gas: No definite shape or volume → ✔
Explanation: These are key characteristics used to distinguish the states of matter.
---
These questions cover fundamental concepts from Bill Nye’s "Phases of Matter" episode, including:
- States of matter
- Phase changes
- Role of temperature and energy
- Real-world examples (refrigeration, dry ice, liquid nitrogen)

Let me go through each question one by one and give you the correct answers with clear explanations:
---
1. The universe is made of ________.
Answer: Matter and energy
Explanation: The universe consists of matter (anything that has mass and takes up space) and energy (the ability to do work or cause change).
---
2. What are the three phases (states) of matter?
Answer: Solid, liquid, gas
Explanation: These are the three common states of matter. Solids have a fixed shape and volume, liquids have a fixed volume but take the shape of their container, and gases have neither fixed shape nor volume.
---
3. The only difference between molten (liquid) steel and solid steel is _________.
Answer: The arrangement of particles (or the state of matter)
Explanation: Molten steel is liquid because its particles move freely and are not locked in place, while solid steel has particles arranged in a fixed structure. The substance is the same—just in different physical states.
---
4. What is needed to change a phase of matter?
Answer: Energy (heat) or removal of energy (cooling)
Explanation: To change from solid to liquid (melting), heat energy is added. To change from liquid to gas (evaporation), more heat is added. Conversely, cooling removes energy and causes phase changes like freezing or condensation.
---
5. How does a refrigerator cool food and drinks?
Answer: By removing heat from the inside and releasing it outside
Explanation: Refrigerators use a refrigerant that absorbs heat from the interior (causing cooling) and releases it into the surrounding air through the back coils. This process relies on evaporation and condensation of the refrigerant.
---
6. Changing a SOLID to a LIQUID requires _________.
Answer: Heat energy (or adding energy)
Explanation: Melting a solid into a liquid requires energy to break the bonds holding the particles together.
---
7. Nitrogen is a liquid at _________ °C. Nitrogen makes up _____ % of the air that we breathe.
Answer: Nitrogen is a liquid at -196°C. Nitrogen makes up 78% of the air we breathe.
Explanation: Nitrogen boils at -196°C under standard pressure. It's the most abundant gas in Earth’s atmosphere.
---
8. What happened to the onion after soaking in the liquid nitrogen?
Answer: It became very brittle and shattered easily (or froze instantly)
Explanation: Liquid nitrogen is extremely cold (-196°C). When an onion is placed in it, it freezes rapidly, making it fragile and prone to breaking apart.
---
9. Dry ice is solid _________.
Answer: Carbon dioxide
Explanation: Dry ice is solid carbon dioxide (CO₂). It sublimes (turns directly from solid to gas) at room temperature without becoming a liquid.
---
10. The slower molecules move, the _________ the temperature.
Answer: Lower
Explanation: Temperature is a measure of the average kinetic energy of particles. Slower-moving molecules have less kinetic energy, so the temperature is lower.
---
11. Absolute zero is when molecules come to a complete _________.
Answer: Stop (or rest)
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 thermal motion.
---
12. Circle the appropriate answer for each phase of matter.
*(This likely refers to a diagram or multiple-choice section where students match properties to solids, liquids, and gases.)*
Example:
- Solid: Definite shape and volume → ✔
- Liquid: Definite volume, no definite shape → ✔
- Gas: No definite shape or volume → ✔
Explanation: These are key characteristics used to distinguish the states of matter.
