Question

The substance xenon has the following properties:

normal melting point:161.3 Knormal boiling point:165.0 Ktriple point:0.37 atm, 152.0 Kcritical point:57.6 atm, 289.7 K

1-At temperatures above 289.7 K and pressures above 57.6 atm, Xe is a (solid/liquid/gas/supercritical fluid)

2-Xe does not exist as a liquid at pressures below ( ) atm.

3-Xe is a _________solid/liquid/gas/supercritical fluid at 20.0 atm and 144.6 K

4-Xe is a _________solidl/iquid/gas/supercritical fluid at 0.370 atm and 172.4 K.

5-Xe is a _________solid/liquid/gas/supercritical fluid at 1.00 atm and 162.0 K.
