At a pressure of 1 atm, the temperature 90.7 K is called the fill in the blank 1 of CH4 . The normal boiling point for CH4 is at K The triple point pressure for CH4 is atm The critical pressure for CH4 is 45.7 atm. At temperatures above 190.7 K and pressures above 45.7 atm, CH4 is a . CH4 is a at 9.20×10-2 atm and 117 K. CH4 is a at 1.00 atm and 106 K. CH4 is a at 36.1 atm and 82.7 K.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
