Not all types of wood float, but most do. The fact that wood generally floats is simply because it is less dense than water.
Adding Salt to the water increases the density of the water, and therefore makes it weight more per capita. This in turn causes the salty water to push down with more force then water with no salt, causes things that may not float, to float, and things that already float in normal water, to float higher in salty water.
Gravity makes a ship float. Gravity pulls harder on the mass of water than the air inside the ship. In this way the water is pulled under the ship, instead of the ship being pulled under the water.
I have a marker which float in water.
The density of Saturn is less than the density of water on Earth. But you'll never see Saturn float, because that would require a really gigantic pool.
A lotus plant adapts itself to live in water by developing leaves and stems that waxy in texture and essentially "hydrophobic." Lotus plants have achieved the hydrophobic effect.
Two adaptive features of lotus- Lotus leaves are wide and disc-shaped, which allows them to float on water. Their generous surface area allows them to absorb a large amount of sunlight.
because they have long stem .
A cork has a low density. It is lower then water. That causes it to float.
The surface area of the raft displaces the water forcefully which causes float
most probably, the weight of lotus must much smaller than its width or lets just say volume. and here buoyancy place an important role.
What causes it to sink or float is the density. The density of water is 1.0. If the object's density is more 1.0 then it sinks, but if the object's density is less then 1.0 then the object will float.
The density of ice is lower than the density of water.
Its average density is a lot less than water
Ice has a lower density than water.
Pine cones float because they are less dense than the water, so they float. When you put them in right-side-up, the air gets trapped under the water. This causes the air bubbles to push up which makes the pine cone float.
Seeds float with the current.
