Liquids:
* Have a definite volume but no definite shape. They take the shape of their container.
* Molecules are closely packed but can move around each other. This allows them to flow.
* Examples: water, oil, honey, blood.
Gases:
* Have no definite volume or shape. They expand to fill their container.
* Molecules are far apart and move freely. This allows them to expand and compress.
* Examples: air, oxygen, carbon dioxide, helium.
Composition of Fluids:
The exact composition of a fluid depends on its specific type. Here are some examples:
* Water: Made up of hydrogen and oxygen atoms bonded together as H₂O molecules.
* Air: A mixture of gases, primarily nitrogen (N₂) and oxygen (O₂).
* Blood: A complex fluid containing plasma (water, proteins, electrolytes), red blood cells, white blood cells, and platelets.
Important Note:
* Fluids are not always made of just one type of molecule. They can be mixtures of different substances, such as solutions or suspensions.
* The properties of a fluid depend on the interactions between its molecules. For example, the viscosity of a liquid is determined by how strongly its molecules attract each other.
