Not at the start because as you all ready know that a football does float on water. But after a long period of time it will finally of lost the air inside and them yes it will finally sink. But this just doesn't happen in sea water it will happen in any water. I hope that has asked your question.
It is better to use the muddy puddle water than the seawater because of the salt
Seawater, then pure @ 4 degrees C.
Because the salt in the seawater dries it up. Salt is very bad for any form of plant
A solution.
The four MAIN IONS in seawater in descending order of abundance are: CI: Chloride Na: Sodium SO4: Sulfate Mg: magnesium Found in Leckie-Yuretich: Investigating the Ocean, Page 114, Seawater Salinity: The salt of the Ocean
Seawater is more dense than freshwater. Therefore the seawater would sink lower than the freshwater. Ships do indeed stay higher in seawater because of the higher density or specific gravity of seawater over freshwater
yes
It depends on the density of the cube, not the length of its side.
The most important factor affecting seawater density is its temperature. As temperature increases, seawater density decreases, causing it to expand and rise. Conversely, as temperature decreases, seawater density increases, causing it to contract and sink.
They open valves to allow seawater to enter the ballast tanks outside.
The ship will sink slightly. Salt water is denser there for heavy objects will float more in it. When the ship goes back to fresh water the density decreases and the ship lowers again. This link gives extra information and some simple experiments for you to try at home. http://www.kidsgen.com/school_projects/how_ships_float.htm
The buoyancy factor of steel in seawater is less than 1, meaning steel will sink in seawater due to its high density. The exact buoyancy factor will depend on the specific composition and weight of the steel. Additional factors such as surface area and volume will also influence the buoyancy of steel in seawater.
yes. think about balloons: a ballon with helium will float while a balloon with good ol' air will sink
1912 thats when the titanic sink
A density current forms when denser seawater moves towards less dense seawater. This movement occurs due to differences in temperature and salinity, causing the denser water to sink and flow along the seabed towards less dense seawater. This process helps distribute nutrients and maintain ocean circulation.
Density. The saltier water is the heavier (per unit volume) it is. The saltiest water doesn't always sink though. Seawater density is dependent on temperature, salinity and pressure. Most often the effects of temperature are dominant in determining vertical stratification.
Seawater is water with salt in it
