If you were to go there you would either float...or not float. You choose;)
float
No. Gravity on Venus is close to what it is on Earth.
Venus would float on the water
The Submarine would 'Float' or 'Sink' to the level of bouyancy equal to where it would here on Earth due to the similar gravity. Since the atmosphere at the surface of Venus is equal to being underwater about one kilometer, short of damage from heat (467 degrees C) any object that would float at that pressure in water on Earth would float on Venus. A submarine could float at a point where the atmosphere is about 3-4 bar (about 45-60psi) which would be about 40 Kilometers high, and runs about 110C for ambiant temp. It could 'Dive' by taking in the ambiant air, but would not be able to 'Vent' the chamber afterwards to rise. The prop also wouldn't work as well. Even though the atmosphere has a similar pressure to water, it is still a gas, and unlike water, compressible. A 'ballon' made with a thick metal skin would be able to float in a temperate region without much problem. Except for the one problem both the 'Submarine' and the Ballon would have - the temperate region has high winds, and clouds made out of Sulfuric Acid. Beyond that, smooth sailing!
it will float as long as it is not fully covered water.

Venus is exactly the same size as Venus.
if you mean can we get to venus. I say that we cannot land on venus. It is capable to orbit venus
Yes
When considering distance from the sun, the planet that come after Mercury is Venus.
No. There is no life on Venus.
This was to investigatethe atmosphere of Venus.
