Question

the phase diagram for methane shows a triple point at 90.7k and 0.115 atm and a critical point of 190.6k and 45.3 atm. assume methanes phase diagram behaves in a similar fashion to those which you have already seen for water and carbon dioxide. one of saturns moons, titan, was discovered to have signs of methane. the temperature at the surface of titan is about 94k, and the pressure about 1.5atm. which phase would be the most likely for methane to be in at the surface of titan? 1. solid 2. supercritical fluid 3. gas 4. liquid

Explanation:

Brief Explanations

Para determinar la fase del metano en la superficie de Titán, comparamos la temperatura (94 K) y la presión (1.5 atm) con los puntos crítico y triple del metano. El triple punto es de 90.7 K y 0.115 atm. La temperatura de 94 K es mayor que la del triple punto (90.7 K) y la presión de 1.5 atm es mayor que la del triple punto (0.115 atm). En un diagrama de fases similar al del agua o dióxido de carbono, a una temperatura por encima del triple punto y presión por encima del triple punto, el metano estará en fase líquida.

Answer:

  1. Liquid
