True.
All materials can be melted or thermally decomposed.
Solid. And it remains solid until it reaches very high temperatures, there are only a handful of other metals that have higher melting points.
A solid-state diode is a diode where the electrons flow through only solid materials. Nearly all diodes in common use are solid-state.
I think Helium is the only standout that cannot be made into a solid at low enough temperature. All solids may be made into a gas /plasma at high enough temperature. add. note. Maybe He can be made solid with sufficient pressure - but maybe only the Sci-fi writers know.
Sublimation.The frozen CO2 changes directly from solid into a gas. It can only remain in a solid form because of the very low temperatures it is kept at. At room temperatures it begins to change (sublime) from a solid directly into a gas (skipping the liquid state).
Plasma only occurs at very high temperatures.
Sodium is a solid metal at room temperatures. In the body it only exists as an ion of one of it salts.

Computer disks are not volatile. Only RAM is.
Coal, distilled in a retort to expel the volatile content and leave the carbon as a spongy-looking solid called "coke".(Strange - there are several versions of this question, suggesting to me poor teaching or text-books that focus only on the chemistry and not the overall process, purpose?and materials.)?

Probably it is because these materials (gases, for example) are less dense than rocky materials, and the solar wind has had a long time to push such materials farther out.
Almirah is a solid at room temperature, because it will only be liquid at its melting point and the room temperature is not its melting point.
Yes mars is solid and not made of some gasses. The only problem is to get your materials to mars and building it.
