The task is to classify each item as a
solid,
liquid, or
gas. Here's the solution with explanations for each:
---
1. Milk
-
Classification: Liquid
-
Explanation: Milk is a liquid because it flows and takes the shape of its container.
---
2. Cookie
-
Classification: Solid
-
Explanation: A cookie has a definite shape and volume, which are characteristics of solids.
---
3. Oxygen
-
Classification: Gas
-
Explanation: Oxygen is a gas at room temperature and pressure. It does not have a fixed shape or volume unless contained.
---
4. Fish
-
Classification: Solid
-
Explanation: A fish has a definite shape and volume, making it a solid.
---
5. Pencil
-
Classification: Solid
-
Explanation: A pencil has a rigid structure and a definite shape, so it is classified as a solid.
---
6. Maple syrup
-
Classification: Liquid
-
Explanation: Maple syrup flows and takes the shape of its container, which are properties of liquids.
---
7. Shampoo
-
Classification: Liquid
-
Explanation: Shampoo is a liquid that flows and can be poured, fitting the definition of a liquid.
---
8. Carbon dioxide
-
Classification: Gas
-
Explanation: Carbon dioxide is a gas at room temperature and pressure. It expands to fill any container it is placed in.
---
9. Ice cube
-
Classification: Solid
-
Explanation: An ice cube is made of frozen water, which has a definite shape and volume, making it a solid.
---
10. Paint
-
Classification: Liquid
-
Explanation: Paint flows and can be spread over surfaces, indicating it is a liquid.
---
11. Oil
-
Classification: Liquid
-
Explanation: Oil flows and takes the shape of its container, so it is classified as a liquid.
---
12. Salt
-
Classification: Solid
-
Explanation: Salt (sodium chloride) has a crystalline structure and a definite shape and volume, making it a solid.
---
13. Water vapor
-
Classification: Gas
-
Explanation: Water vapor is the gaseous form of water. It expands to fill any container and has no fixed shape or volume.
---
14. Gasoline
-
Classification: Liquid
-
Explanation: Gasoline is a liquid that flows and can be poured, fitting the definition of a liquid.
---
15. Helium
-
Classification: Gas
-
Explanation: Helium is a gas at room temperature and pressure. It expands to fill any container and has no fixed shape or volume.
---
16. Sand
-
Classification: Solid
-
Explanation: Sand consists of small, solid particles that do not flow like a liquid or expand like a gas. Each grain of sand is a solid.
