Which statement is true about phase diagrams?
A)Every phase diagram has only one triple point.
B)The slope of the liquid-solid phase boundary line is typically negative.
C)The triple point temperature is the lowest temperature where a liquid can exist.
D)The critical temperature is lower than the triple point temperature.
E)The critical temperature is lower than the normal boiling point.

Question

Quizplus · Accepted Answer

The triple point temperature is the temperature where the three phases (solid, liquid, and gas) can coexist in equilibrium. This temperature is the minimum temperature at which a substance can exist in its liquid state. Therefore, statement C is true. Statements A, B, D, and E are false.
