You can observe water droplets on the surface of a chilled bottle because the temperature of the atmosphere is a different temperature to that of the temperature in the chilled bottle.
What is the difference between a normal ship and a submarine?
Normal ships are designed to move on the surface of the water. Submarines are designed to be able to submerge and travel under the water's surface, as well as on the surface. When normal ships go down, they stay down. Submarines are able to come back up after they go down. All American submarines are nuclear powered. With the exception of Aircraft carriers, surface ships are powered conventially.

How does a submarine dive under water from the surface?
Submarines dive by opening vent valves that allow sea water to push air out of their ballast tanks.
Why do submarines work?
Submarines have ballast tanks in them.........when it has to go deep down, the ballast tanks are filled with water, which increases its average density in regard to water(Relative Density).....and when it has to come up to the surface it empties the ballast tanks...and it rises. That's it.
How can submarines float and sink?
Submarines change their depth by use of ballast tanks. To dive, they open their tanks so that they become filled with water. They also angle their dive planes. To surface, they pump the water out of their tanks and fill them with pressurised air.
