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?

Answers

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.
