he herped so hard he derped a baby durr

>>2079582
What... kind of gas though?
I'm having real trouble pictuing it.

co2 never becomes a liquid, fun fact.

it would be a dense gas.

you can't picture it because you couldn't actually see it.

YOU KNOW THAT GAS YOU EXHALE? IF YOU HEAT IT UP IT GETS LESS DENSE. LIKE EVERYTHING ELSE.

>>2079606
Dude. If Helium can become a liquid, then CO2 can totally become a liquid. Please try again.

>>2079601
Temperature on Venus is 460'C, or 860'F.
Air pressure is around 85 to 90 times Earth pressure.

>Carbon dioxide has no liquid state at pressures below 5.1 standard atmospheres (520 kPa).

>>2079625
Thanks for linking to the page to prove yourself wrong. The phase diagram is clearly shown, and there are temperatures and pressures for which CO2 is a liquid, solid, and gas. What the hell are you trying to say?

>>2079622

The air pressure is a result of the presence of 95% fucking carbon dioxide heated to 500 degree fucking celsius. The particles themselves are MORE gas-like than the carbon dioxide on this planet.

>>2079639
>CO2 on Venus
>460'C
>liquid
Nope.avi
That is what I'm trying to say.

>>2079639

This man is not who you were talking to earlier dipshit, he even has a tripcode. He was proving you CORRECT.

>>2079650
You said, verbatim, "co2 never becomes a liquid, fun fact.", and I replied that that is patently false.

OP, it looks like this

Are you high?

>>2079717

Funny when I see that picture I think a drizzly day in the mountains. Not fucking 460 C outside.

Venus is such a failplanet.

>>2079723
have another

more venus info

Venus is my second favorite planet in our solar system.

>>2079723
This is a picture I snapped on a hike a few kms from my house.

>>2079740
What is that in the pic? A broken piece of metal?
I'd say it's wood, but wood would char on Venus.

>>2079763

pffft hahaha 0/10

>>2079773
implying wood would combust on venus

>>2079773
>implying wood would combust on venus

>>2079785
It would char, not burn. There's a difference.
Charcoal, for example, is made by heating wood in a retort, where all of the oxygen has be sealed out, so that the wood does not burn.

>>2079773
It was a protective covering for the camera that was ejected when the lander was on the ground.

There was another camera on the opposite side, but the pressure prevented the 'lens cap' from coming off.

The camera sat behind a thick protective quartz window.

>>2079781
It's true. Only about 80,000,000 kilometers away.

>>2079796
May not be entirely clear from that post, but the quartz window and the cap on the ground are two different things.

The cap protected the quartz window, the quartz window protected the camera.

>>2079793

awww fuck now I feel like an ass

>>2079806
There's nothing wrong with being wrong.

>>2079806
Why?
Most people, and most scientists would confuse charring and burning. I only know because I make my own willow charcoal. Get oxygen into the retort, and you've just ruined the batch.

>>2079816

Other than, you know. The fact that you are wrong.

>>2079643
I'm still having trouble picturing what a gas that dense means for, like... buoyancy.
Would some common materials, placed on the ground, float upwards into the sky...?

(That's a function of surrounding pressure in relation to the density of an object, right? So anything that would float up at 2,500 feet below the ocean would do the same here?)

If you built a bathysphere to explore Venus's surface, would you have to weight it down with ballast to get that far down or... what?

>>2079824

just because I made a snide remark and turned out to actually be wrong. Thus making you look like an awesome scientist dude and making me look like a tool. s'all cool though I don't mind being corrected

Wolfram for the rescue

Not quite so severe, some things would be bouyant though.

In fact one of the most promising means of colonizing Venus is to place aerostats in the upper atmosphere around 50-60km altitude.

Our atmospheric composition would act as a lifting gas. Hydrogen and helium would act as very effective lifting gases. You could place a bouyant laboratory staffed by researches in the upper Venusian atmosphere.

>>2079872
That said, there are still enormous technical/engineering issues.

Although in my opinion far less than would be needed for a successful colony on Mars.

1. You need protection from sulphuric acid, because the best altitude for habitation is right around the sulphuric acid clouds.

2. Getting off the planet again could be rather problematic. Landing from space on a floating bouyant platform might also be problematic.

>>2079872
So basically... the pressure on Venus is compatible with sky-whales, even though the chemistry is not?

>>2079902
It's all a matter of whether or not it's bouyant.

But yes, you could probably have something like a skywhale, assuming it's filled with giant sacs of lifting gas.

Is that a euphamism for "trying to dock two submarines underwater at speed?"
