can something exist in more than one “state” at the same time without changing composition? Ie can a single drop of water technically be a solid, gas and liquid at the same time?

Question

Further to that, can something exist in 4 states (solid, liquid, gas, plasma)?

Answer 1

Yes for liquid and gas at the same time that is called a supercritical fluid.

For three states at the same time its called the triple point. [https://en.wikipedia.org/wiki/Triple_point](https://en.wikipedia.org/wiki/Triple_point)

A quadruple point cant exist to my knowledge.
