A supercritical fluid refers to a substance
A)above both its critical temperature and its critical pressure.
B)at its triple point.
C)that is in the liquid crystal state.
D)with a viscosity of zero.

Question

Quizplus · Accepted Answer

A supercritical fluid occurs when a substance is heated and compressed above its critical temperature and critical pressure, causing it to have properties that are intermediate between those of a gas and a liquid. This state is characterized by a high density, low viscosity, and high diffusivity, making it useful for a variety of applications such as extraction, purification, and chemical synthesis.
