solid,
liquid, or
gas based on its physical state. Here's the explanation and solution for each item:
---
1. Pencil
-
Classification: Solid
-
Explanation: A pencil is a solid object because it has a definite shape and volume. It does not flow or expand to fill a container.
---
2. Hot air
-
Classification: Gas
-
Explanation: Air, regardless of temperature, is a gas. It has no definite shape or volume and will expand to fill any container.
---
3. Milk
-
Classification: Liquid
-
Explanation: Milk is a liquid because it flows and takes the shape of its container but has a definite volume.
---
4. Oil
-
Classification: Liquid
-
Explanation: Oil is a liquid because it flows and takes the shape of its container but has a definite volume.
---
5. Cake
-
Classification: Solid
-
Explanation: A cake is a solid because it has a definite shape and volume. It does not flow or expand to fill a container.
---
6. Carbon dioxide
-
Classification: Gas
-
Explanation: Carbon dioxide is a gas at room temperature and pressure. It has no definite shape or volume and will expand to fill any container.
---
7. Glasses
-
Classification: Solid
-
Explanation: Glasses are made of solid materials like plastic or glass, which have a definite shape and volume.
---
8. Oxygen
-
Classification: Gas
-
Explanation: Oxygen is a gas at room temperature and pressure. It has no definite shape or volume and will expand to fill any container.
---
9. Shampoo
-
Classification: Liquid
-
Explanation: Shampoo is a liquid because it flows and takes the shape of its container but has a definite volume.
---
10. Water vapor
-
Classification: Gas
-
Explanation: Water vapor is the gaseous form of water. It has no definite shape or volume and will expand to fill any container.
---
11. Syrup
-
Classification: Liquid
-
Explanation: Syrup is a liquid because it flows and takes the shape of its container but has a definite volume.
---
12. Rock
-
Classification: Solid
-
Explanation: A rock is a solid because it has a definite shape and volume. It does not flow or expand to fill a container.
