Question

The state of matter in which the molecules are closest together is the _____.

liquid phase
solid phase
gas phase

Answer 1

The state of matter in which the molecules are closest together is the **solid phase**. In solids, the molecules are tightly packed together in a fixed arrangement, which gives solids a definite shape and volume. In liquids, the molecules are close together but can move past one another, and in gases, the molecules are far apart and move freely.
