they float
tiny hair on the roots and a swollen leaf stalk
Using water is an example, anything that is less dense than water will float on water. Anything that is denser than water will sink in water.
Many specimens have a high enough porosity that they can float on water until ... This is what produces the enormous rush of high-pressure gas from the vent. ... has a specific gravity of less than one, giving the rock an ability to float on water.
This would include the term "buoyancy", which is not limited to objects that float. An objects whose weight is less than the water displaced by it would float. But an object could become suspended below water by the upward force of bouyancy, which acts on all objects in liquid.
Yes, water density will affect an object's ability to float.
No. Buoyancy refers to the ability to float in water.
Salt water has salt (!) in it, ego it is denser and takes more weight to displace it; the reason things float in whatever. The denser the liquid, the higher things float
There is no difference on how well a toy boat will float in water depending upon the temperature. The ability for an object to float is if it can displace more than its own weight in water, which doesn't depend on the temperature of the water.
Hardness, ability to float or sink in water and so on.
It is the displacement of the vessels weight and the freeboard remaining of a vessel that determines whether a vessel will float and or sink. A ship will float higher on salt water (salt water is denser) than if on fresh water (less dense).
the ability of an object to float on water. If the object's density is greater than 1 it will sink. If the object's density is less than 1 it will float.
