A solid float on water if the density is lower than the density of water.
a solid ceramic object would sink. however, if the object is displacing enough water proportional to it's weight, then it will float. If you put an empty glass bowl in the water, it will float; but if you allow water in, it will sink. This applies to ceramics.
Depends on the medium, and whether the ball is solid or not. A solid ball would float on mercury, sink in water. If it were hollow enough (or filled with, say, cork) it would float in water.
float
Some of the ash will, but there will be bone fragments that will sink to the bottom of the water. You can purchase water soluble urns that can be placed in the water. They float for a few minutes and then sink.
it is hollow so it will float
It depends on the density of the solid, liquid, or gas. If the density is lower than water it will float. (Water's density is about 1). Also, if the volume of the solid, liquid, or gas is bigger than the mass then it will also float. It will sink if the solid, liquid, or gas's density is higher than water's density. :)
I have a marker which float in water.
No, it is not. Oil and water do not mix. If you pour oil into water, the oil will float to the surface. If you pour water into oil, the water will sink to the bottom and the oil will float on top.
That depends on the relative densities of the solid and the liquid. If the solid is denser than the liquid, the solid will sink. If the liquid is denser, the solid will float.
does Arsenic float or sink
it will float as long as it is not fully covered water.
The mass of an object alone is not enough to determine whether it will float in water. You need to know the object's mass and its volume; in other words, its density. A kilogram of solid lead will sink in water. A kilogram of styrofoam will float. If an object is less dense than water it will float; if it is denser it will sink.
