The Correct Answer and Explanation is :
I will create a labeled molecular-level diagram of fluorine ((\text{F}_2)) at 40K, 70K, and 100K, along with a 300-word explanation. Stay tuned.
Here is a molecular-level depiction of fluorine ((\text{F}_2)) at different temperatures: 40K, 70K, and 100K. Now, here’s a detailed explanation of what happens at each temperature:
Explanation of Fluorine at Different Temperatures
Fluorine ((\text{F}_2)) is a diatomic molecule held together by a strong covalent bond between two fluorine atoms. However, the interactions between separate (\text{F}_2) molecules are due to London dispersion forces (LDFs), the weakest type of van der Waals interactions. These intermolecular forces influence fluorine’s phase transitions.
1. At 40K (Solid State)
- Physical State: Fluorine is in the solid phase because the temperature is below its melting point (53.53K).
- Molecular Arrangement: The (\text{F}_2) molecules are tightly packed in a crystalline lattice, minimizing movement.
- Forces Present: Strong London dispersion forces (LDFs) hold the molecules together. These forces arise from temporary dipoles due to electron movement.
2. At 70K (Liquid State)
- Physical State: Fluorine is in the liquid phase, since it is between the melting and boiling points.
- Molecular Arrangement: The molecules are still attracted to each other but have more freedom of movement, allowing them to slide past one another.
- Forces Present: Weakened London dispersion forces, as molecules have higher kinetic energy, weakening intermolecular attractions.
3. At 100K (Gas State)
- Physical State: Fluorine is in the gaseous phase because the temperature is above its boiling point (85.03K).
- Molecular Arrangement: The molecules are far apart and moving rapidly in random motion.
- Forces Present: No significant intermolecular forces, only the strong covalent bonds within each (\text{F}_2) molecule remain intact.
This behavior highlights how molecular interactions change with temperature, dictating the physical state of fluorine.
