Answer: Here's my answer, sorry if its detailed.
Step-by-step explanation:
Solids are a type of matter that have a definite shape. They maintain their shape and do not easily change their arrangement. Solids also have a definite volume, meaning they occupy a specific amount of space. Examples of solids include rocks, ice, and wood.
Liquids, on the other hand, do not have their own shape but take on the shape of their container. They have an indefinite shape. However, liquids do have a definite volume, meaning they still occupy a specific amount of space. Examples of liquids include water, oil, and milk.
Gases have an indefinite shape and tend to spread out to fill their container. They do not have a specific shape and can expand to occupy any available space. Gases also have an indefinite volume, as they can be compressed or expanded depending on the conditions. Examples of gases include oxygen, nitrogen, and carbon dioxide.
To summarize:
1. Solids have a definite shape and volume.
2. Liquids have an indefinite shape but a definite volume.
3. Gases have an indefinite shape and volume.
These properties of matter are described by the kinetic molecular theory, which explains how particles in different states of matter behave based on their motion and interaction with each other.
