If the ocean was 200 km deep, and given Titan’s acceleration due to gravity of 1.35 m/s2, the pressure at the bottom would be 2700 bars. Assuming an average temp of -180C, at that pressure, water would form a type of ice that is denser than liquid water.
- jakogut 3y agoDoesn't ice melt under pressure? Is it possible this could still be liquid water at those pressures and temperatures?
- hirsin 3y agoIce only melts under pressure right around the freezing point - it's that weird overhang on the phase diagram, maybe to around minus fifty C. But by -180C it's always solid.
- pvaldes 3y agoIf is saltwater the pressure should be even higher, plus the weight of 40km of ice. 200Km is uncharted territory for earth, with a maximum depth of almost 11 Km. But life is able to stand until 800 bars at least. More than this is metabolically defiant in organisms made of cells. Vertebrates can survive 760 bars at least. The majority of the volume on is oceans could be empty and barred to life, but there is still a lot of space for conventional life (and Titanlings could be very different and defy our standards)
