The triple point of iodine is at 0.12 atm and 115^$\circ$C. Thus, liquid I₂ A) is more dense than I₂ (s). B) cannot exist above 115^$\circ$C. C) is liquid at room temperature. D) cannot have a vapor pressure less than 91 torr.

Question

Quizplus · Accepted Answer

The triple point is the only condition under which all three phases (solid, liquid, and gas) can coexist. Below this pressure, the liquid phase cannot exist, so the vapor pressure of liquid I2 cannot be less than 91 torr (0.12 atm).

The Triple Point of Iodine Is at 0 ∘\circ∘ C Thus, Liquid I2 A) Is More Dense Than I2

The Triple Point of Iodine Is at 0 $\circ$ C Thus, Liquid I₂
A) Is More Dense Than I₂
