Which state of matter has a rigid fixed shape and volume?
Gas
Liquid
Plasma
Solid
The correct answer is: Gas
The correct answer is D. Solid. Solids have a rigid fixed shape and volume due to the strong intermolecular forces holding their particles closely together. Gas (A), liquid (B), and plasma (C) do not have a rigid fixed shape. Gases and liquids take the shape of their container, while plasma is an ionized gas that does not have a fixed shape or volume like solids do.
