As O₂(l)is Cooled at 1 Atm,it Freezes at 54 $\Delta$ H for the I

question 113

Multiple Choice

As O₂(l) is cooled at 1 atm,it freezes at 54.5 K to form Solid I.At a lower temperature,Solid I rearranges to Solid II,which has a different crystal structure.Thermal measurements show that $\Delta$ H for the I $\to$ II phase transition is -743.07 J/mol,and $\Delta$ S for the same transition is -17.0 J/K mol.At what temperature are Solids I and II in equilibrium?

• A)13.6 K
• B)43.7 K
• C)19.8 K
• D)98.2 K
• E)They can never be in equilibrium because they are both solids.

Definitions:

Alveolar Epithelium

The thin layer of cells that lines the alveoli (air sacs) in the lungs, playing a key role in the exchange of oxygen and carbon dioxide.

Vital Capacity

Greatest volume of air that can be exhaled from the lungs after a maximum inspiration.

Compliance

Change in volume (e.g., in lungs or blood vessels) caused by a given change in pressure.

Pulmonary Edema

An accumulation of fluid in the lungs' air sacs, leading to impaired gas exchange and potentially causing difficulty breathing.
