The substance hydrogen has the following properties: normal melting point: 14.0 K normal boiling point: 20.3 K triple point: critical point: 7.1x102 atm, 13.9 K 12.8 atm, 33.2 K At temperatures above 33.2 K and pressures above 12.8 atm, H2 is solid liquid H2 does not exist as a liquid at pressures below at gas supercritical fluid H2 is a H2 is a H2 is a at 7.10x102 atm and 29.2 K. at 3.53 atm and 5.0 K. at 1.00 atm and 17.1 K. Submit Answer

Explanation / Answer

At temperature above 33.2K and pressure above 12.8 atm H2 is - Supercritical fluid :: as these are conditionabove the crirical point .

H2 does not exist as a liquid at pressure below - 7.1x10-2 atm :: as below triple point pressure hydrogen exis as solid or gas

H2 is a gas at 7.1x10-2atm and 29.2 k :: above boiling point and at triple point pressure

H2 is a solid at 3.53atm and 5 k :: below melting point and above triple point pressure

H2 is a liquid at 1atm and 17.1 k :: between metling and boiling point and above triple point pressure and below crticial point pressure
