Correct answers require the right questions! Our current understanding of Einstein’s equation $E = m {c}^{2}$ indicates that matter is more correctly a form of energy than the other way around.

#### Explanation:

Chemically, matter is usually classified as solid, liquid or vapor, with plasmas occupying a separate form of their own. While matter may be converted to energy relatively easily (combustion, thermonuclear processes) it is more difficult to convert energy into matter.
