The critical temperature and pressure of CS₂are 279°C and 78 atm, respectively. At temperatures above 279°C, CS₂can only occur as a _. A) liquid and gas B) solid C) liquid D) gas E) supercritical fluid

Question

Quizplus · Accepted Answer

Above the critical temperature of 279°C, CS₂ exists as a supercritical fluid, which has properties of both a liquid and a gas. It exhibits properties such as high density like a liquid and low viscosity and surface tension like a gas. Therefore, the best choice is E.

The Critical Temperature and Pressure of CS2 are 279°C and 78
