It is all to do with the density. Water has a density of 1g/cm^3 (1 gram per centimetre cubed). Anything that has a density of less than this will float in water, but anything that has a density greater than this will sink.
other way around, buddy =)
density!

An object that is denser than water or another liquid sinks.
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.
No. A toothpick and a tiny stone both have small mass, but one floats and the other sinks. A passenger ferry and a large boulder both have large mass, but one floats and the other sinks. It's not the mass that determines whether the object will float. It's the ratio of its mass to its volume ... the number known as the object's "density".
An object will float if it is less dense than the water (or other liquid). If it is denser than the water, it sinks.
It has to do with density. If an object is less dense than water (for example, oil), it floats. If an object is more dense than water, it sinks.
If the object is less dense than water it will float, but if it is more dense it will sink.
Bouyancy determines whether an object sinks or floats.
Yes, that's correct. If an object has a density lower than that of water, it will float. If it sinks, then its density is greater than that of water.
Yes, the weight of an object affects whether it sinks or floats in a fluid. An object will sink if its weight is greater than the buoyant force acting on it, causing it to displace an amount of fluid equal to its weight. Conversely, if the buoyant force is greater than the weight of the object, it will float.
