Which correctly lists the types of matter, in terms of their atoms, in order from least tightly packed to most tightly packed?

Question

solid, gas, liquid
solid, liquid, gas
gas, solid, liquid
gas, liquid, solid

Answer 1

The correct order from least tightly packed to most tightly packed in terms of the arrangement of their atoms is:

gas, liquid, solid

In gases, the atoms are far apart and move freely. In liquids, the atoms are closer together but can still move around. In solids, the atoms are tightly packed in a fixed structure.
