True or false: All solids, liquids, and gases have density

Answer: True

Explanation:

solids and liquids have high densities because their particles are packed closely together, whereas gases have low densities because their particles are very far apart. A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape. The change from solid to liquid usually does not significantly change the volume of a substance.

True.

Solids, liquids, and gases all have mass.
