Define critical point. Group of answer choices The temperature and pressure below which a supercritical fluid exists. The temper
ature and pressure above which a supercritical fluid exists. The temperature and pressure are equal. The temperature and pressure are not equal. The temperature and pressure where liquid, solid, and gas are equally stable and are in equilibrium.
The temperature and pressure below which a supercritical fluid exists.
Explanation:
Critical point is a region on the phase diagram where fluid phases (liquids and gases) have the equal density.
This is caused by increased temperature and pressure of the fluid particles in a confided container. Supercritical fluids exist in a state above critical point.
Valance electrons are the outermost electrons in an atom. There are five electrons in the third layer of the phosphorus atom. So your answer is five valance electrons.
