Could an ocean exist with an atmosphere of 10% that of Earth?

The boiling point of that pressure is 115 degrees F.  Let’s say 20 million square km with an average depth of 8,000 feet and a 8% salt content. The temperature range through the year is 140 degrees to -20 degrees. One day is 30 hours. 


One year is 250 days.

    So... on average, the ocean would evaporate, increasing the pressure of that atmosphere until it was saturated; it would rain or mist just as much as it would boil or evaporate. Provided there was enough water *in* the ocean, yes - it could exist, until  the water molecules were removed through solar wind.

    For starters, you cold have an earth with an average temperature lower than 115 degrees.

     It would Evaporate

    The lowest temperature is -20 Fahrenheit and the highest is 140 degrees Fahrenheit. I suspect lots of evaporation with the higher temperatures and rain in the temperatures with milder temperatures and the water freezing in the lower temperatures. Yes I likely will remain liquid under these conditions. I think it would resemble a fog all the time because of the evaporation and perception happening more frequently than Earth.
