Question

Explain the properties of liquids in terms of the molecules or atoms that compose them.

liquids have higher densities than gases because the atoms or molecules of liquids _____ liquids have an indefinite shape and definite volume because atoms or molecules of liquids_____

Answer 1

Liquids have higher densities because of the strong intermolecular forces between molecules. Liquids have an indefinite shape and definite volume because the molecules can move past each other.

Step-by-step explanation:

Liquids have higher densities than gases because the atoms or molecules of liquids are packed relatively close together. This is due to the **strong intermolecular attractive forces** between the particles in the liquid, which hold them close together and make the liquid more dense. In contrast, gases have much larger separations between molecules, resulting in low densities.

Liquids have an indefinite shape and definite volume because the atoms or molecules of liquids can move past or slide over one another. While the intermolecular forces hold the molecules together, they are not fixed in place like in a solid. This allows the liquid to adopt the shape of its container since the molecules can move and flow.
