Question
Choose the statements that correctly describe the phase diagram below.
(Select all that apply.)
__The liquid/gas line really extends farther than is shown in this diagram.
__The liquid phase of this substance can exist under conditions of 1.2 atm and temperature from approximately 200 to 300 K.
__The critical point occurs at 1.75 atm and 400 K.
__The solid/liquid phase line extends farther than shown in this diagram.
__If the temperature is raised from 50 K to 120 K at a pressure of 1 atm, the substance boils at 100 K.
Explanation / Answer
statements ii , iii , iv correctly describe the diagram
that is
a)The liquid phase of this substance can exist under conditions of 1.2atm and temperature between 200 to 300K
b) the critical point occurs at 1.75 atm and 400K
c) The solid/liquid phase line extends farther than shown in this diagram.
