Question

4 how do molecules in a gas compare to those in a solid? a molecules in a solid have a fixed structure, while molecules in a gas spread out b molecules in a solid have a loose shape, while molecules in a gas have a fixed shape c molecules in both a solid and in a gas move freely and do not have a fixed shape

Explanation:

Solids have tightly packed molecules in a fixed, rigid structure that holds their shape. Gases have molecules with very weak intermolecular forces, so they spread out to fill their container and have no fixed shape. Option A correctly describes this contrast. Option B reverses the shape properties, and Option C incorrectly states solid molecules move freely and lack a fixed shape.

Answer:

A. Molecules in a solid have a fixed structure, while molecules in a gas spread out
