Based on the phase diagram for methane, what happens to methane as it is heated from 250 to 180°C at a pressure of 10 atm? 4 10³ 102 10 1 10-1 Pressure (atm) 10-2 10-3 10-4 Solid Liquid -200 -100 Supercritical fluid Gas 0 Temperature (°C) Previous Answers 100 It boils at about 180 °C. It sublimes at about 180 °C It reaches the triple point at about 180 °C. It melts at about-180 C. It condenses at about - 180 C X Incorrect; correct answer withheld by instructor When we move left to right across the phase diagram at 10 atm, we cross the point at which all three of the curves meet, or when all three phases are in equilibrium at about 180 °C. This is the triple point.
