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.
An object will float on water if it has less density than the water. Or than any other liquid on which it is supposed to float.
An object that can float on water or other fluids is called buoyant.
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.
Not necessarily. An object's ability to float in a liquid depends on the density of the object compared to the density of the liquid. Even though an object may float in oil, it may not float in water if the object is more dense than water.
other way around, buddy =)
The amount of water needed to make an object float depends on the object's density and volume. The volume of water displaced by the object should be equal to or greater than the volume of the object for it to float. Adding more water will increase the buoyant force.
The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.
Many things can float in water. An object will float based on 2 main factors. They are density and shape. If an object is too dense, it will sink. But why would shape matter? The shape of the object affects how the water is displaced. If the weight of the water displaced is more than the weight of the object that is touching the water, the object will float. So the shape affects how much water is displaced therefore determines if an object will float.
An object's ability to float in water is determined by its density relative to the density of water. If an object is less dense than water, it will float. If an object is more dense than water, it will sink. The shape and size of the object also play a role in determining its ability to float.
If an object has a lower density than water, it will float. If an object has a higher density than water, it will sink. This is because objects will displace an amount of water equal to their own weight, and if the weight of the water displaced is greater than the weight of the object, the object will float.
The weight of the object must be equal to the weight of the water it displaces in order for the object to float in water. This is known as Archimedes' principle. If the object is less dense than water, it will float; if it is more dense, it will sink.
If the density of an object which is equal to one(Which is also the density of the water), the object will neither sink nor float but it will be unstable, sometimes you will see the object sink then float. In other words the object is unstable in water....XD
