Whether an object will float or sink in water will depend on its volume and weight. If the weight of the displaced water is more than that of the body, the body will float. On the other hand if the weight is the displaced water is less than that of the body, the body will sink. Again if both of them are equal, the body will partially sink.

Sea water contains salt. So its density is more and consequently, the weight of the sea water is more. So there is more chance of a ship to float in sea water than in river water.

ADD: It depends on the density of the object. If an object is denser than water, it will sink. If it is less dense than water, it will float.

What determines whether objects float or sink in water?

The density of an object compared to the density of water determines whether it will float or sink. If the object is less dense than water, it will float. If it is more dense, it will sink.


Will a fork sink or float?

A fork will sink in water, as it is denser than water. The density of an object determines whether it will sink or float in water.


Do ceramic float or sink?

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.


How do you determine if something will sink or float in water?

To determine if an object will sink or float in water, you compare the density of the object to the density of water. If the object is denser than water, it will sink. If the object is less dense than water, it will float. The principle of buoyancy, which states that an object will float if it displaces an amount of water equal to its weight, also plays a role in determining whether something will sink or float.


What will an object less dense then water do when placed in water float or sink?

If an object is less dense than water will it float or sink?

It will float.


Can you use density of an object to predict whether it will float or sink in water?

Yes, you can use density to predict whether an object will float or sink in water. If the density of an object is less than the density of water (1 g/cm³), it will float. If the density of an object is greater than the density of water, it will sink.


What happens when an object is placed in water?

it will sink of it will float.


How can you use density to determine if an object will sink or float a fluid?

If the density of an object is lower than water then it will float, if the density is higher it will sink.


Will a marble float in water?

No, a marble will sink in water because it is denser than water. The density of an object determines whether it will float or sink in water.


Does the denser object sink in water?

It depends! If it is more dense than water then it will sink. If not it will float.
