They are lighter in density as compared to solids. Gas are compressible, whereas not all solids. Gases exhibit better flow characteristics than solids. Gases readily react with other substances. All solids are seen by the naked eye whereas some gases are not.
Gas is mostly invisable, Solids are visable. Take a container for a example, Solids cant take the shape, a Gas can spread out through the whole container. (SCF)
There is no set temperature for solids. Each element is different. At room temperature we have solids, liquids and gases. Therefore the temperature for a solid is different for each element.
Structure. Solids have definite shape and definite volume. Liquids have definite volume but indefinite shape. Gases have both indefinite shape and indefinite volume.

Flow. Gases and liquids can both modify their shapes.
Gases
Yes they do.

When cooled gases change to liquids (usually) and then solids Solids don't change to gases upon cooling

While solids and gases are very different - one can be physically grasped and the other cannot - they also share similarities. For examples, solids and gases are alike because they both have matter, mass and weight.
Though both can act as fluids liquids are a different and much cooler state of matter. Gases must first become liquids before they can become solids.
I can only tell you that gases are does not have a difinite shape and volume . E.g air / nitrogen / carbon dioxide / water vapour / . . .
some solids,liquids and gases are dangers some are not dangers
Solids have a definite volume and gases have a variable volume
i would say solids but it depends on how good youare with solids or gases. hope this helps :)
the volume of them all stay the same
