Answer 3

Well, let's think about the options here. You have:
a gas (neon gas), a solid (solid copper) and two liquids (liquid nitrogen and liquid mercury). Solids generally have a fixed shape and a fixed volume, for instance a block of metal. Liquids have a fixed volume, but are free to move around to conform to the shape of whatever container they're in. Gas has neither a fixed shape nor a fixed volume. If you increase the pressure, the volume of the gas will decrease. The gas will also expand to fill whatever container is holding it.
So, the answer to this question is NEON gas.
