Question

How could there be 2 phases of oxygen at one temperature?

Answer 1

Answer:

Hey!! Ur answer:

The three phases coexist at a single pressure and temperature. This is known as the triple point and is described by a single point on a phase diagram.

γ-phase: faint blue – forms at 1 atm, below 54.36 K, cubic crystal structure.

δ-phase: orange – forms at room temperature at a pressure of 9 GPa.

ε-phase: dark-red to black – forms at room temperature at pressures greater than 10 GPa. ζ-phase: metallic – forms at pressures greater than 96 GPa.

Answer 2

At room temperature, oxygen has two-phase beta and delta phases.

Explanation:

• Oxygen is a diatomic molecule with lone pair of electrons.
• The oxygen diatomic molecule has two unpaired electrons in pi molecular orbitals.
• Oxygen is in the gaseous phase in ambient conditions and shows a series of phase transitions in compression to liquid and solid.
• These two phases are molecular solids consisting of oxygen molecules as a structural unit.
• At the epsilon phase oxygen occurs as O₈.
• At a single point in the phase diagram, three phases coexist at a single temperature and pressure this point is called the triple point.
