Final answer:
When gas molecules are packed too tightly together, the volume of the gas molecules becomes less significant. The gas molecules repel each other and move farther away from each other.
Step-by-step explanation:
When gas molecules are packed too tightly together, the volume of the gas molecules becomes less significant. As the gas molecules are compressed, they occupy a smaller volume and are closer to each other, resulting in an increase in intermolecular forces. This leads to the gas molecules repelling each other and moving farther away from each other.
