Given an object that is denser than water, how will you make it float?

Any object that enters a fluid will displace some of the fluid. A totally submerged object will displace its own volume. A floating object will displace a volume less than its own


volume!





Any object submerged in a fluid experiences a buoyant force. This is true for both floating objects and submerged objects.





In all cases, the buoyant force on an object is equal to the weight of the displaced fluid.





For floating objects, the buoyant force is equal to the object's weight.





For submerged objects, the buoyant force is less than the object's weight.





Weight = mass x gravity





gravity = 9.8 m/s^2





density = mass / volume





specific gravity = density / (density of water)





density of water = 1.00 g/cm^3 = 1000 kg/m^3





Or try this fun link that has drawings explaining it (its really cool)

lower its density by forming it into a boat like shape.





Steel is much denser than water, but when formed into a baot, it will float. This is becasue the apparent volume of the steel has lots of empty space in it. This empty space added to the volume of the actual steel, make the density lower than 1....therefore, it will float.
increase the water's pressure
Decrease mass per volume (m/v) by adding that mass to a higher volume (say, a boat) or increase the mass/volume of water, by adding mass to the water, increasing its density (say, by adding salt to it). The idea is to get the total mass per volume of your object to equal the mass/volume of water.


(Note, the volumes of your immersed object and the displaced water volume are equal, but the mass per that volume can change).
Change the shape of the object so that it displaces more water than the object weighs. Like a boat.
Give it a large enough surface area.
change its molecular structure so it will float
Put it on a boat.
Add salt to the water.
add a powder to the water that will make the water denser
