Question

which state of matter has the weakest forces between atoms

1. plasma

gas
solid
liquid

Explanation:

In gases, atoms or molecules are far apart and move freely. The intermolecular forces (such as van der Waals forces) are very weak compared to solids (where atoms are closely packed and forces are strong, giving a definite shape) and liquids (where forces are stronger than in gases, allowing liquids to have a definite volume but no definite shape). Plasma also has weak forces as it consists of charged particles moving freely, but in common - state - of - matter comparisons (excluding extreme conditions), gas is the typical answer for the weakest inter - particle forces among the common states (solid, liquid, gas).

Answer:

Gas
