Answer the following question given this paragraph: Refer again to water's phase diagram ( Figure above ). Notice point E, labeled the critical point . What does that mean? At 373.99C, particles of water in the gas phase are moving very, very rapidly. At any temperature higher than that, the gas phase cannot be made to liquefy, no matter how much pressure is applied to the gas. The critical pressure (P c ) is the pressure that must be applied to the gas at the critical temperature in order to turn it into a liquid. For water, the critical pressure is very high, 217.75 atm. The critical point is the intersection point of the critical temperature and the critical pressure. Q: What is the intersection point of the critical temperature and the critical pressure called? A:
Pick your answer from:
(A). instance point
(B). basic juncture
(C). peak point
(D). critical point
(D).
