Question

which molecule is packed tight​

Answer 1

Answer:

A gas can be considered as a compressible fluid. Solid molecules are tightly compacted together, and liquid molecules are little spread out. Gas molecules are very spread out and are full of energy floating around randomly. Gas molecules can fill up any container with no consideration to size or shape.

Answer 2

Answer:

In a solid the molecules are packed tightly together (high density), usually in a definite arrangement (suggesting order).
