Something will sink if it is heaver than the same volume of water, so it depends on the density of the ball. Rock is denser than water so stones sink. However, depending on what a ball is made of it may or may not be heavier than the same volume of water. For example a Golf ball is denser than water so it sinks, but a ping-pong ball is lighter and will float.

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.
Density is the property that causes a ball to sink and a boat to float. If an object is denser than the liquid it is placed in, it will sink, while if the object is less dense than the liquid, it will float.
No. Only pumice (volcanic) stone can float.

No, plasticine is denser than water, so a plasticine ball will sink in water rather than float.
A tennis ball will float in water because it is less dense than water. The air inside the ball helps to keep it buoyant on the surface of the water.
A pumice stone is light weight due to numerous trapped gas bubbles that can cause it to float on water.
it will float as long as it is not fully covered water.
No, a steel ball will not float in mercury, even if it is heated. Mercury is much denser than steel, so the steel ball will sink in mercury regardless of its temperature.
Most stones will sink in water because they are denser than water. However, some types of pumice stones are porous and can float on water due to their low density.
Objects that sink, such as a metal ball, can float if their shape is changed to increase their volume or decrease their density. By changing the shape to increase the volume, such as flattening the ball into a thin disk, the object can displace more water and float. Alternatively, decreasing the density of the object by adding buoyant materials can also make it float.
