Sodium chloride (NaCl), also known as table salt, is a solid at room temperature.

Here's why:

* Solid: The strong ionic bonds between sodium and chlorine atoms form a rigid, crystalline structure.

* Liquid: Sodium chloride melts at a very high temperature (around 801°C or 1474°F).

* Gas: Sodium chloride can exist as a gas at extremely high temperatures.

* Aqueous: This term refers to a solution where sodium chloride is dissolved in water. While sodium chloride dissolves readily in water, it's not the pure compound in its natural state.
