A gas is a substance that does not have a fixed shape or volume. It can expand to fill the space available to it.
The volume occupied by one molecule of water is approximately 0.03 nm^3. This is based on the average volume occupied by a water molecule, which is about 3 Å on each side.
No definite shape and no definite volume. The volume of a gas is a function of the pressure. Increase pressure and the volume will drop. Gasses will expand to fill all the available volume if left to their own device, if no exterior pressure is applied.
A gas can expand or contract depending on the volume of its container. Gases have no fixed shape or volume, and they fill the space available to them. When the volume of the container increases, the gas molecules spread out and the gas expands. Conversely, when the volume decreases, the gas molecules are compressed, causing the gas to contract.
The substance would be in a gaseous state if it had no fixed volume. Gases have no fixed shape or volume and can expand to fill the container they are in.
No. Steam is a gas, thus volume is a variable. (It is often referred to as a vapor since it is usually near its liquid condition.)
The word 'compress' is the opposite of 'expand'.
The best synonym for "expand" in this context would be "increase in volume."

Usually not. They can easily expand into a larger volume, or be compressed into a smaller volume.
The average volume of a water molecule is about 3.4 x 10-29 cubic meters.
Gross volume is the volume at actual condition whereas standard volume is at standard Pressure/Temperature condition.
Collide
The air will expand, increasing the volume
A gas. Gas will expand to fill the available space.
As solids are warmed, they expand and their volume increases. Conversely, as solids cool, they contract and their volume decreases. For liquids, warming causes expansion and an increase in volume, while cooling results in contraction and a decrease in volume. Gases behave differently as they expand when warmed and contract when cooled, with volume being directly proportional to temperature.
