Compared to an empty ship, would a ship loaded w/ a cargo of styrofoam sink deeper into water, or rise?

Deeper. The styrofoam has mass to it, moreso than the air that is currently filling the void space in the boat. Therefore with the added mass the boat will have to displace more water before reaching it's boyancy point. Displacing more water will cause it to sink further in the water.Compared to an empty ship, would a ship loaded w/ a cargo of styrofoam sink deeper into water, or rise?
Due to weight it will sink and that depends on the load. Styrofoam is a tricky part to fool the answers!? Do you know the


answer to this one: What weighs more 1 kg of cotton or 1 kg of metal?
The ship would still sink, but theoretically, if the buoyancy of the styrofoam was equal to or greater than the weight of the whole ship, the boat would not sink. what the other respondends don't seem to realize is, that if the ship is sinking, there WILL be water inside of the ship.
It would sink deeper, of course. A ship loaded with Styrofoam would not be as heavy as one loaded with, say, steel, but it would be heavy enough to sink lower into the water.
sink deeper (the ship would be more dense, not less).... if the ship became submerged, it would float, assuming the styrofoam doesn't float away
It would be deeper. The only bearing on the ships level is the weight of the ship, PLUS the weight of the cargo. What the cargo actually is, is irrelevant.
Sink deeper. Since the ship isolates the water from the styrofoam, it is just weight. The weight could be rocks for all the water knows. However, they HAVE used ping-pong balls to float a sunken ship to the surface so it could be salvaged. They pumped the hold full of them and the air inside of them made the ship bouyant.
The water line on a ship is dependent on the ship's weight, water displaced, and density of the medium that it is floating in.





Have you ever seen an actual cargo ship? If so, you see them loaded and stacked with those seatrain containers. What do you think is inside the seatrain container other than the goods? There is an awful lot of dunnage in there. That dunnage adds weight and does not subtract from it.
twjones is right , unless the ship carry hydrogen or helium ballooms.


So long as the cargos are in the ship and heavier than air the ship will sink deeper.
