To solve the problem, we need to classify each object as a
solid,
liquid, or
gas based on its physical state. Here's the explanation and solution for each item:
---
1. Milk
-
Classification: Liquid
-
Explanation: Milk is a liquid because it flows and takes the shape of its container.
---
2. An ice cube
-
Classification: Solid
-
Explanation: Ice is in a solid state because it has a fixed shape and volume.
---
3. Water vapor
-
Classification: Gas
-
Explanation: Water vapor is water in its gaseous state, which means it has no fixed shape or volume and expands to fill any container.
---
4. A basketball
-
Classification: Solid
-
Explanation: A basketball has a definite shape and volume, making it a solid.
---
5. Oil
-
Classification: Liquid
-
Explanation: Oil flows and takes the shape of its container, so it is classified as a liquid.
---
6. A marshmallow
-
Classification: Solid
-
Explanation: A marshmallow has a fixed shape and volume, even though it may be soft, it is still considered a solid.
---
7. Water
-
Classification: Liquid
-
Explanation: Water is a liquid because it flows and takes the shape of its container.
---
8. Juice
-
Classification: Liquid
-
Explanation: Juice flows and takes the shape of its container, so it is classified as a liquid.
---
9. A piece of notebook paper
-
Classification: Solid
-
Explanation: Notebook paper has a fixed shape and volume, making it a solid.
---
10. A piece of wood
-
Classification: Solid
-
Explanation: Wood has a fixed shape and volume, so it is classified as a solid.
---
11. Tomato soup
-
Classification: Liquid
-
Explanation: Tomato soup flows and takes the shape of its container, so it is classified as a liquid.
---
12. Oxygen (what humans breathe in)
-
Classification: Gas
-
Explanation: Oxygen is a gas at room temperature and pressure, meaning it has no fixed shape or volume and expands to fill any container.
---
13. Helium in a balloon
-
Classification: Gas
-
Explanation: Helium is a gas that fills the balloon and expands to take the shape of the balloon.
---
14. A cotton ball
-
Classification: Solid
-
Explanation: A cotton ball has a fixed shape and volume, even though it is fluffy, it is still considered a solid.
---
15. Carbon dioxide (what humans breathe out)
-
Classification: Gas
-
Explanation: Carbon dioxide is a gas at room temperature and pressure, meaning it has no fixed shape or volume and expands to fill any container.
