Question

which statement best describes the gas in a scuba tank? the gas barely fills its container. the molecules of gas are moving slowly. the gas is compressed.

Explanation:

Scuba tanks hold large amounts of gas (typically air) in a relatively small, rigid container by compressing the gas to high pressure. Gases expand to fill their containers, so a non-compressed gas would not be stored in a scuba tank; gas molecules in a pressurized tank have high kinetic energy and move quickly, not slowly.

Answer:

The gas is compressed.
