Which state of matter exhibits the highest molecular motion, characterized by rapid translation and minimal intermolecular attraction?

The state of matter with the fastest molecular motion is the gas phase. In a gas, molecules move quickly in all directions because the kinetic energy is high and the distances between molecules are large, so there is almost no attraction pulling them together. This rapid, random motion is why gases expand to fill any container. For example, the air in a balloon spreads out to fill the whole balloon because the air molecules are constantly moving and barely interacting with each other.
