Here's a breakdown:
Containers that definitely contain molecules:
* Any physical container: This includes bottles, jars, boxes, rooms, buildings, even the Earth's atmosphere. All these things hold matter, and matter is made of molecules.
* Living organisms: Cells, tissues, organs, and entire bodies are all containers that hold molecules necessary for life.
Containers that might contain molecules:
* Vacuum chambers: While designed to be empty, even the most sophisticated vacuum chambers still contain a tiny number of molecules.
* Interstellar space: While very thin, interstellar space does contain a few atoms and molecules.
Containers that don't contain molecules:
* The vacuum of space (outside of stars and planets): The vast emptiness of space is considered a true vacuum with no molecules present.
Important Note:
Even when we talk about containers holding molecules, we need to consider the state of matter. For example:
* Gases: Molecules in a gas are spread out and move freely. They're not actually "contained" in a traditional sense.
* Liquids: Molecules in a liquid are close together but can move around.
* Solids: Molecules in a solid are fixed in specific positions, held together by strong bonds.
