I've latley been thinking quite heavily on this topic.

and I thought of a strange solution, the problem with depth is pressure?

 

Using something so simple.

 

If water pressure is the problem eliminate it entirely using heated evaporation

Imagine a Metal Chassis, a Gridded layer of Thermal coiling.

another layer of metal that is cooled.

it wouldn't have to be heavy, infact the lighter the better.

less weight would be ideal for the most mobility possible

If it does Null the pressure it would be constantly evaporating a layer of water

Visibility wouldn't be possible due too the steam.  I suggest no windows, only cameras too see.

That won’t work, for too many reasons to mention. Just remember that the boiling point of water increases with pressure and you may start to understand the problem.

 

Hint: at the extreme pressures encountered by a bathyscaphe, water cannot be boiled at all and just becomes a super-heated liquid.

Yes. Here's a phase diagram showing the pressure and temperature at which the vapour and liquid phases cease to be

separate:

There used to be a lovely experiment in the Science Museum in London, in which you could watch a bulb with freon in it be heated up until the meniscus between liquid and vapour vanished. I remember one 6th Form physics lesson in which the teacher handed out underground tickets and told us to leave our books and go, by ourselves, off to South Kensington to see it. 

 

Sadly it's gone now. Too much like real physics for the modern audience, which seems to be just little kids gawping at space capsules.

a bathyscaphe is a manned sub.

(I suggested there would be no visibility and cameras to see)

If this is true why do volcanic vents create vapor.

 

A British scientific expedition has discovered the world's deepest undersea volcanic vents, known as 'black smokers', 3.1 miles (5000 metres) deep in the Cayman Trough in the Caribbean.

 

The ocean ranges in depth from 0 to more than 36,000 feet deep. The average depth of the ocean is about 12,100 feet, which is more than 2 miles! The deepest known point in the ocean is more than 7 miles below the ocean surface.

 

 

The key is instantaneous Evaporation.(not boiling)

Evaporation is a different process to boiling. The first is a surface effect that can happen at any temperature, while the latter is a bulk transformation that only happens when the conditions are correct.

 

Water  especially salt water is just not one big thing , they are separate molecules and layers.

contact evaporation would burn a layer.

Water evaporates at any temperature above freezing, the hotter the temperature the faster it will dissipate. Water is already turning to steam when it reaches (100 degrees Celsius/ 212 degrees

That seems to fit in your ratio as well

As you have written (copied and pasted): Evaporation is a different process to boiling. The first is a surface effect.

Do you understand what is meant by "surface effect"?

Water does not evaporate under water!

 

And, if you have looked at the graphic posted by exchemist, you will have seen that water does not boil at pressures greater than 218 atm.

 

Pressure under water increases by 1 atm per 10 meters of depth

 

218 atm correlates to 2,180 meters depth.

 

The vents in your video are 5,000 meters deep and the pressure is much more than 218 atm so water at that depth does not boil.

 

What you are seeing is jets of super heated water escaping from the vent and carrying mineral deposits along with them.

 

Anything else?

Physics today is mostly kids using google and not understanding a bit of what they have read. 

(and of course just making up sh1t)

There are other types of volcanic vents. Some are found along deep submarine mountain ridges in the ocean floor, and others on continental land, and they’re known as hydrothermal vents(Black Smokers). These types of vents develop when underground water comes in contact with the hot magma; it dissipates, and finally escapes through earth´s crust, rising as steam and gas into the ocean or the atmosphere.

 

Stop talking about boiling in evaporation.

They are two completely different things.

 

 

The vents in your video are 5,000 meters deep and the pressure is much more than 218 atm so water at that depth does not boil.

(No)

The user is finding out the overall work that is assigned for the experiment so need to proceed it as per requirement to
