A submarine fills a special storage area known as ballast with water in order to increase its density. This allows it to dive deeper into the ocean. When a submarine needs to rise rapidly, compressed air is used to push the water out of the ballast. What effect does replacing the water in the ballast with air have on the submarine?
Answer:
The submarine will rise.
Explanation:
To get a submarine to surface, the main vents in the top of the tank are closed and high-pressure compressed air is blown into the ballast tanks, forcing the water out through the flood ports at the bottom of the tank. This increases the vessel's displacement.

A submarine fills a special storage area known as a ballast with water in order to increase its density. This allows it to dive deeper in the ocean. When a submarine needs to rise rapidly, compressed air is used to push the water out of the ballast. What effect does replacing the water in the ballast with air have on the submarine?
Answer:
the submarine floats after replacing the water with the compressed air
Answer:

Slow cooling of hot magma leads to the formation of ___________ crystals
Answer:
Slow cooling leads to the formation of large crystals. If the crystals remain undisturbed while cooling, they grow according to a regular pattern. Magma closer to the surface cools much faster than magma that hardens deep below ground. With rapid cooling, there is no time for magma to form large crystals.
