pressurised water is filled in the outer cell. and air is removed.
You drag the word "submarine" itself onto the submarine. Then you wait for it to sink.
The Confederate submarine 'H L Hunley' was the first submarine to sink an enemy ship
A submarine is to spy on ship movements and if necessary sink ships
put the word submarine on it
A submarine can sink and float in water because it has ballast tanks that can be filled with water to make it sink and with air to make it float. By adjusting the amount of water and air in the ballast tanks, the submarine can control its buoyancy and stay submerged at a desired depth or rise back to the surface.

You grab the word submarine and pull it down.
You have to bring the word submarine down to the bottom of the screen.
The H. L. Hunley was the name of the Confederate submarine that was the first combat submarine to sink an enemy ship.
both. they are able to control it
The density of a submerged submarine is about the same as the density of the fluid it is submerged in, which is typically seawater. This allows the submarine to float or sink based on its buoyancy and weight.
A submarine is made from strong material so it can withstand the tremendous pressure at depths.
