Is it possible to make a planet full of water and at the same time without life?

I think yes. No calculation here. What you need to do is a planet with a thick layer of water, so water on the bottom would be iced by the pressure. For example, on Earth, it would be oceans deeper ...

Is it possible to make a planet full of water and at the same time without life?

A planet with water but no life is 100% plausible. But your atmospheric composition is not plausible — a large amount of free oxygen without life is difficult to explain, and large amounts of both ...

Is it possible to make a planet full of water and at the same time without life?

It just hasn't happened yet We lack data to know how inevitable life, but chances are that earth-like planets exist where life just hasn't happened yet. Perhaps in-opportune changes in climate cut off ...

Is it possible to make a planet full of water and at the same time without life?

With the caveat that since we've only ever seen life here, so all of these answers involve some speculation, there's a few things you might suggest. Lack of Phosphorous (or some other vital piece) ...

What are the climatic consequences of existing on a planet with a dense and fairly cold atmosphere?

Not Possible At this solar distance, star luminosity, and atmospheric composition, the planet should be hot, not cold. While you got your Mass/Solar Distance/Bond Albedo/Greenhouse calculations ...
