Carbon doesn't exist in just one state like water (solid ice, liquid water, gas steam). It has multiple forms, each with its own properties:

* Solid: This is the most common form of carbon. Examples include:

* Diamond: Extremely hard and transparent, with a high melting point.

* Graphite: Soft and slippery, good conductor of electricity, used in pencils.

* Fullerene: A cage-like structure of carbon atoms, known for its unique properties.

* Amorphous carbon: A non-crystalline form of carbon, found in charcoal and soot.

* Liquid: Carbon can exist as a liquid at extremely high temperatures, around 3500°C (6332°F).

* Gas: Carbon exists as a gas in the form of carbon dioxide (CO2), which is a major component of the Earth's atmosphere.

So, the answer depends on which form of carbon you're talking about.
