If to cool temperature of the Venus like Earth's temperature then what will be pressure on solid surface of the Venus?Will it be like pressure on Earth's surface?

According to this

http://en.wikipedia.org/wiki/Atmosphere_of_Venus

most of the atmosphere on venus is carbon dioxide.

Cooling it to roughly the temperature of the Earth wouldn't stop it being a gas.

So essentially all that gas would still be there. On average it would move closer to the surface so it would be attracted more by gravity (but not much).

On the whole, I don't think it would make much difference to the pressure.

It certainly wouldn't be anything like the pressure here on Earth.

Due to the extreme pressure on Venus, if you cooled it down to earth temps you would get a planet covered by solid CO2. On Venus now CO2 is a super critical fluid.

That would aprroximately keep the pressure at ground level as said JC, or 92 bar

cooling to mean 288K would bring CO₂ to the limit of gas and liquid

http://en.wikipedia.org/wiki/Carbon_dioxide , especially

so CO₂ would be gaseous at altitude, with some liquid existing near the ground locally in colder regions. These seas could not preempt all the gas, whose pressure is needed to keep some liquid.

 

I have no suggestion for a practical method.

Thanks for the answers.
