    Undergrad Can a planet with a thin atmosphere have oceans?

    I believe I'm asking it wrong. I'm simply wondering does water boil when water is above boiling point or when the atmosphere at the surface is above boiling point.

    Undergrad Can a planet with a thin atmosphere have oceans?

    If the nights are cool how could water boil in the daytime? I mean I thought it takes water a longer time to reach boiling point than air. Assume 1 day on the planet is 24 hours.

    Undergrad Can a planet with a thin atmosphere have oceans?

    What if the temperatures in a location vary from 55 C in the summer days to 0 C in Summer nights? Would water boil during the summer day or would it stay liquid?

    Does Atmospheric Pressure or Temperature Determine the State of CO2?

    Here's where I'm confused is it the partial pressure of Co2 that determines which state its in or the total atmosphere? Because if in this scenario the temperature were -40 F Co2 would be liquid with the total atmosphere but it would be gas at partial pressure.

    Does Atmospheric Pressure or Temperature Determine the State of CO2?

    The partial pressure is 0.2 bar so it would be gas. However with the whole atmosphere is would be liquid.

    Does Atmospheric Pressure or Temperature Determine the State of CO2?

    Let's say you have a 20 bar atmosphere of 95% nitrogen, 3% oxygen, 1% argon and 1% Co2 cooled to 0 F. Would Co2 be liquid or gas?

    Undergrad Can a planet with a thin atmosphere have oceans?

    Let's say their is a Earth sized planet orbiting a sun like star in its habitable zone. This planet has a tilt and rotation rate similar to Earth. The planet however has an atmosphere of 0.1 bar. The planet orbits its star close enough to have an average temperature of 12 C. From what I...

    Graduate Can an eccentric planet be habitable?

    Its just the temperature extreams sound like a lot from perihelion to aphelion. However it could be good as rink of a runaway greenhouse and icehouse would be unlikely.

    Graduate Can an eccentric planet be habitable?

    So basically its possible to go from an ice age at aphelion to a hot house stage at perihelion.

    Graduate Can an eccentric planet be habitable?

    Wait so it would get 20% hotter which is an extra 56k at perhilion and 12% colder which is an extra 33.6 k at aphelion? That scary.

    Graduate Can an eccentric planet be habitable?

    I'm curious how extreme the temperatures would be.

    Graduate Can an eccentric planet be habitable?

    Let's assume an planet with Earths mass and radius orbits a G2V type star at 1 au. This planet would have an the same tilt, rotation rate and atmosphere of 1 bar as Earth. However the planets eccentricity would be 0.3. How would this greater eccentricity effect this planet?

    Can a Mercury sized moon support an atmosphere?

    Could the moon enter that gas ring and recapture the gas though? I should mention that I wasn't talking about an Earth thickness atmosphere because with a 0.064 Earth mass moon its unlikely I was more in the lines of an atmosphere 0.01 atm. Interestingly I found a gas retention chart and with...

    Can a Mercury sized moon support an atmosphere?

    Yes it would but since it is receiving 70% less sunlight than Earth I would think there could be reasonable temperatures even with the extra tidal heating.
