Carbon at room temperature is solid.
solid...
Non-metals typically exist in solid or gas phases at room temperature, with some non-metals like iodine and bromine being in a liquid phase. Examples of non-metals in the solid phase include sulfur, carbon, and phosphorus.
Indium can be solid, liquid or gas. At room temperature, indium is a solid.
state or phase
The butane phase diagram shows how butane can exist as a solid, liquid, or gas depending on the temperature and pressure. It illustrates the boundaries between these states and the conditions where each state is stable.
Carbon Dioxide can be a solid, liquid or gas. At standard temperature and pressure, it is a gas.
Covalent.Every compound can exist as a solid, liquid, or gas, given the right temperature and pressure. This is also true of every element, with the single exception of helium, which has no solid phase, no matter how cold it is. Helium is unique.
Gas at room temperature
Atoms of all elements exist in the state of matter known as the gas phase.
just like you
It is a solid.
That will not happen unless matter is undergoing a phase change and the temperature you are measuring is that of the matter undergoing the phase change.
