* They can flow: This means they can take the shape of their container. Think about pouring water into a glass, or filling a balloon with air.
* They are compressible: You can squeeze them into a smaller space. This is why you can compress air in a tire pump or squeeze a bottle of liquid.
* They have no fixed shape: This is related to flowing; they take the shape of their container.
However, it's important to note that liquids and gases have some key differences:
* Liquids have a fixed volume: A liter of water will always be a liter of water, even if you pour it into a different container. Gases, however, can expand or contract to fill their container.
* Liquids have stronger intermolecular forces: This means the particles are more attracted to each other and held together more closely than in a gas. This is why liquids have a more defined shape than gases.
So, while both liquids and gases can flow and be compressed, they have distinct properties that set them apart.
