Problem 11.63
The fact that water on Earth can readily be found in all three states (solid, liquid, and gas) is in part a consequence of the fact that the triple point of water (T = 0.01 C, P = 0.006 atm) falls within a range of temperatures and pressures found on Earth. Saturn's largest moon Titan has a considerable amount of methane in its atmosphere. The conditions on the surface of Titan are estimated to be P = 1.6 atm and T = -178 C. As seen from the phase diagram of methane given below, these conditions are not far from the triple point of methane, raising the tantalizing possibility that solid, liquid, and gaseous methane can be found on Titan.Part A

Explanation / Answer
At the pressure of 1.6 atm and -178C, the methane will be present as lqiud
Hence the correct answer is Option B
The correct answer will be Option D (both vaporization and sublimation) since it will be going from the liquid state to the gaseous state
