The substance oxygen has the following properties: normal melting point: 54.8 K normal boiling point: 90.2 K triple point: critical point: At temperatures above 154.6 K and pressures above 49.8 atm, O₂ is al O₂ does not exist as a liquid at pressures below O₂ is a at 42.3 atm and 47.4 K. O₂ is a at 1.50x10-3 atm and 97.2 K. O₂ is al at 1.00 atm and 78.6 K. atm. 1.50x10-3 atm, 54.4 K 49.8 atm, 154.6 K
In this context, we'll explore how oxygen behaves under different temperatures and pressures based on its known properties:
Normal melting point: 54.8 K: This is the temperature at which solid oxygen changes into liquid oxygen under standard atmospheric pressure.
Normal boiling point: 90.2 K: This is the temperature at which liquid oxygen changes into gaseous oxygen under standard atmospheric pressure.
Triple point: 1.50x10^-3 atm, 54.4 K: The triple point represents a unique set of conditions at which all three phases of a substance (solid, liquid, and gas) coexist in equilibrium.
Critical point: 49.8 atm, 154.6 K: The critical point represents the highest temperature and pressure at which a distinct liquid phase of the substance can exist.
